Right. It is the same problem like with HTML where ThML is based on: unnecessarily long tag
names blow up the file size without addional information. The specifications of ThML were 90K in
version 0.93 (PDF) and 240K in version 1.0 (HTML) - this is not due to the new features ...
Another issue is the ability to memorize the tag names when learning a markup language.

As you said before, what fields are to be introduced depends on the markup of the text. We will
never have more detailed supplementary information than the markup provides (right, Jerry,
translation independent verse information is of course an exception; anyway, that is not the matter
here, talking about publication data or something).
ThML header information is IMHO the most detailed about-the text-information at the moment, and it
is indeed "publication data".

What is an LL(1) parser? You know, my little understanding .-)
