I won't touch your first two strikes, but the third requires
a response.

The most thorough implementation of SGML to date appears to
be CALS, the emerging Defense Department standard for
documentation.  If you haven't looked at SGML for two
years, then you probably missed CALS.

CALS does address graphics, tables, and equations.
It sort of cheats on graphics by choosing three formats
from among the many, but hey, why invent another format?
The tables spec has gone through a major revision and
appears to address most of the needs of describing
complex tables.  The equation part was adapted from ISO TR
9573 written by Anders Bergland.

The latest CALS spec also provides a method for identifying
a default format for each text element.  That way you
can have your text and format it too |).

The baseline tag set of CALS provides actual tag names and
definitions that will become some kind of standard merely
by the weight of the DoD.  Several vendors of publishing
software are providing CALS compliance, which will also help
make it a defacto standard for document interchange.
Of course, I don't know of anybody that is actually doing
this yet, but it is certainly feasible now.
