The current XFA spec is at http://partners.adobe.com/public/developer/en/xml/xfa_spec_3_3.pdf (all previous version since 1.0 have also been published).

hmm, didn't know docs were publically available..
I've found this:
seems to be long reading, 412 pages :) I'll have a look at it, thanks.
are you aware of some other docs, or is this the best source?

You should test that option out before you go down that path, as it might not work out anyway.
for now, it seems to work, of course it's possible that after some SAP upgrade, it'll just stop working, which is just another reason why I would'n like to stick to such workaround.. :(
