I agree. I have only just discovered a week ago that something like:
<!DOCTYPE BODY SYSTEM "html20.dtd">
<BODY>
<P>Hello world!</P>
</BODY>
could be an allowable use of SGML. If I had realised this earlier I could
have saved weeks of work in my CML DTDs.
I have to say that the SGML community is *not* good at marketing the
language - I don't *think* it deliberately keeps it opaque. It has proved
extremely difficult to get hold of good newbie information on (say)
architectural forms, HyTime, etc. Pleased to see some postings on XML-DEV
about it but I don't appreciate things normally till I see a piece of
software doing useful work :-) [No criticism to James Clark and those who
have implemented everything, but there aren't many household applications
yet.]
