I forgot about IADS, but yet, that too. FWIW. EBT's DynaText did not
require DTD's (but could take advantage of them), and I think
SoftQuad could be used without them too. In all cases, the subset was
similar to XML, and in (I believe) all cases, the stylesheets were
more powerful than CSS in that they could also define hypermedia
behaviour.

Don't forget Steve DeRose and DynaText, which I would personally
argue was superior to SoftQuad.

Yep, and led by people wanting more powerful capabilities than those
offered by HTML etc. Even now many of the core benefits that were
desired are missing in the WWW.
The fact is that anyone with a reasonable amount of SGML experience
ended up using a core subset similar to XML. Ultimately there was
little new in XML, because it was based on something with a fairly
long history. Some things, like I18N and explicit DTD-less support
were good additions.
