Thanks for the suggestions, all.
Seems The CTL SYS still might be my best bet, even though I am aware that it requires frequent bag-emptying.
The reason I need a truly-compact extractor is because I do not drive, and therefore plan to integrate my chosen extractor into a mobile tool cart, similar to Timothy Wilmots' MFTC, which I'm sure quite a few of you are familiar with:

Looking at that Festool CTL and judging by how often I empty the dustbag on my Kss40. I say it's not worth it for sawing. probably better suited for sanding

There's also the Bosch Ventaro. Had one once, but was a bit disappointed. It has an amazing 1400w in a roughly rectangular box about the same as a Sys Midi. The (albeit short) hose, vac & blower (inflater) tools and an delta-head air turbine sander, spare sanding papers & dustbag all self contained within its briefcase style clamshell.
First the good. At 1400 watts its the most powerful vac & blower that I've ever encountered. It literally would blow my 2 Festo/ol extractors into the weeds. The blower is amazingly effective for cleaning up machinery of swarf etc. The sander is simarly effective, despite being unpowered by anything other than the vacuum created, whilst simultaneously efficiently extracting any sawdust generated. Over time, as the bag fills, the sander's effectiveness & "power" gradually diminishes. All in all a pretty remarkable overall package for an absolutely bargain-basement price.
It's cheap. Mine cost the princely sum of Au $80 (GBP 45-50?) when new. I've seen second hand examples (albeit in Europe) sell for mere pennies on Flea-Bay. The case is made from a softer, more flexible ABS type of material, that easily withstands worksite abuse far better than the supposedly stronger but more brittle grade of plastics used by the Festo/ol range. The modern Festool's extractor casings are notoriously fragile and poorly designed.
The design, make & manufacture is generally up to the usual Bosch standards. Mine was reliable & well made. It actually has a reasonable quality feel to the overall package. Manufacture is in Turkey, which at a stretch could therefore be described as of European origin. The fact that Turkey is a Middle Eastern nation or at least part of the "Orient" as in the final destination of Agatha Christie's Orient express is both germane & salient. Lands east of the Bosporous are commonly regarded as Asian.
Now the bad. Those 1400 watts are pretty noisy. When used indoors (its more natural habitat) that sound is uncomfortably amplified with a clear absence of any sound insulation. Ear defenders are a must. It's bags are ridiculously small for general cleanup operations. A mere 5 or 6 litres of dust space in palpably insufficient, & will require frequent bag renewal/replacement. There's no auto functionality either.
The onboard hose is ludicrously short: a mere 1.5m at a guess. There's just no reach available. You have to have that noisy bloody beast right "there" alongside you & in uncomfortable proximity to do any sanding work, where the relative silence of operation of the air turbine sander is comprehensively trumped by those 1.4 killer-wasps of motor and impeller noise. An aftermarket hose (35mm dia. works best) from any reasonably priced source (i.e. anywhere/anybody but Festo) is another must. Turbulence within longer corrugated hoses will inevitably lead to a slight diminution of overall suction & airflow.
There's no volume (speed) control. So it's always loud. This will over time become wearing on the operator's stamina and resolve. That's why I likewise despise Festool's clone of the Ventaro, the stupid Sys-Vac or CTL-Sys. These lunchbox type mini-vacs lack the all-important bypass motor cooling systems of proper dust extraction equipment, whereby cleaner & cooler air to the motor is always available independently of the actual extraction function. Instead they must rely on the "dirty" preheated air from whatever tool is attached to the hose end. Whether that particular tool requires a little or a lot of airflow to operate & extract efficiently (yes, it does matter) is irrelevant to these types of vacuums. they always must run flat maggot to maintain that severely compromised cooling airflow. They're actually more or less just a rather dodgy but powerful domestic vac with a puny dustbag shoved into a small suitcase!
There's likely to be a "me too" type coming from (I'm guessing here) Starmix/Metabo, which Metabo proudly showed off at the latest Bau conference/trade fair. It probably has the highly desirable auto on/auto off function of the best extractors. It also featured an innovative (probably low voltage relay-driven) on/off switch on the hose end. That'd be the absolute cat's pyjamas for cordless saws, drills etc. What a clever idea! Whether they take a more appropriate & "professional" approach to speed variability and motor cooling than the others is currently an unknown. Here's hoping.
As an aside, with some shrink-wrap insulating sleeves, available from any reliable electrical wholesaler, a pair of shears/scissors & a hot air gun you can make your own custom vac hose & tool adapters in about 30 seconds flat! Run a short length of braided copper inside between the 2 ends & you have antistatic electrical continuity inbuilt too!

Further to my earlier posts in this thread, I'm trying to locate pics of compact vacs, both for my own reference and (I hope no one objects) to post in this thread as a useful reference for others (if anyone does object, please don't suffer in silence - just tap me on the shoulder with a friendly PM). I have no affiliation with any manufacturer - I choose my tool brands on the merits of the specific type of tool being purchased at any particular time, rather than being a fanboy of any single brand (as seems to be rife with many customers of a well-known green-coloured competitor). I have a fair bit of DeWalt, some Bosch, Metabo, Mafell, too. When I personally refer to a compact vacuum, I mean really compact, as in CTL-SYS or similar. I have been unable to locate an uber-compact Metabo vacuum extractor, so if anyone can actually directly point me to this or indeed any other really compact competitor, please let me know. Here is the well-known (4.5L capacity, requiring frequent emptying) CTL-SYS:   Importantly, the CTL SYS offers a power take-off socket, to start the vacuum when the powertool is started, which is a nice feature for such a compact, minimalist vac, and, as others have remarked, a very useful (essential?) feature. Also noteworthy is that the hose garage is removable, to make the CTL SYS even more compact:  and here is a Milwaukee (7.5L capacity), albeit with the significant caveat that it is battery-powered (18v or 28v versions available):  I suppose this mains-powered Makita is relatively compact, in terms of volume (22L), but I don't consider it compact in terms of form-factor. It's not much smaller than a Henry:  Here is a more compact (but battery-powered) Makita:  Dunno about you folks, but I can't really take battery power seriously for a vacuum extractor.

There's also the Scheppach HD2P... £70 - maybe that says it all! No experience of it - used to do good quality stuff many years ago, seems to no longer be the case.

Yeah, Scheppach used to make some nice light-industrial machinery, but have definitely gone downmarket in recent years (as have Record Powertools / Elektra Beckum, IMO).
Having said that, £70 isn't much of a risk, for that compact vac. Purely on the basis of that, it might (might...) be worth a punt...

I have the ctl-sys. It ok. The dust bag needs emptying quite a bit as the suction reduces quite often. Anflike most of these tools. You have to pay extra for bits like: long life dust bag, attachments and i ended getting the sys-cart as its not convenient using the strap. So in all, I would of been better of with the CT range. I still use my Henry now and again. They are very convenient. Just make sure you the use dust bags otherwise the motor blows. I just noticed the CTL SYS power take-off is rated at only 1200w max, but the MT55CC is rated at 1400w (probably a bit more). Do you (or anyone else reading this) successfully use an MT55CC fed via the socket on the front of the CTL SYS? That 1200w rating might scupper my plans to buy a CTL SYS for use with me MT55CC, entirely.

Hi - just returning to this with an update. Having shelled out a lot on other new tools I was keen to spend minimally (for now) on an extractor, as well as having something as small as possible. I take different kit on different jobs so needed something that takes up very little space in my car. As an interim solution when starting a job I picked up a 'MacAllister' 16 litre vac from B&Q . . For £30. 5 filter bags cost £10. It's compact, light as a feather, has power take off and surprisingly good suction. The hose of course needed adapting but the bags will take lots of rips oc 18mm ply before filling up. Admittedly it's like wearing cheap hi-tech squash shoes (I have 2 pairs!) with a fine suit. But it does a job I accept the valid points about Hepa ratings and efficiency - but bear in mind also that using a lower spec extractor is a lot better than nothing at all, which I still see going on a lot on some jobs. It's a constant trade-off. When I have a bigger budget and/or vehicle I can upgrade to a better extractor system. In the mean time I was able to satisfy the immediate need for compact dust extraction and invest in a nailer that has helped my work no end.

Someone should offer a 6 meter hose that you pass though a window or door connected to something with a remote switched motor / armature similar to an electric leaf blower that blows into a canvas bag outdoors. No more hepa. (or clients)
(and yes, I’m going out right now to hook up the leaf blower mulching bag and try this… better yet I just found the perfect aerofix accessory vac to draw crazy suction independently of the saw vac)

Sounds like a wise choice. Auto switching is great in a vac, but there's nothing "magical" about it, and certainly nothing to justify spending a King's ransom on. OK, maybe the filtration is not as effective or even "safe" as a HEPA certified version, but it doesn't sound as though you're actually exposing yourself to any large amounts of aerosolised toxins anyway, so given your intended use (a basic saw/s & maybe some sanding/cleanup) it's prudent to reassess your actual needs. Would a lime green machine costing some 10 times as much be any more effective at the allotted tasks anyway, especially given the extortionate prices charged for consumables too?

The low noise level is worth a lot imo.
