(X)HTML has been criticized for missing good structuring
properties (sections are not headings, div is only a workaround ...).
Examples in the book by David Megginson's book.

Hm. I think this is the job of a good editing environment.
Ada has a grammar. The grammar can be mapped to an internal
XML representation that is internal to the editor, o.K..
 But why touch Ada?
A fairly simple XSL program can be used to extract plain Ada source text from
a combined source text document that includes graphics, reference, etc.,
in addition to the Ada source text.
A fancy XSL program can do all sorts of project specific processing.
 For sure, if you only touch some non-Ada piece of a source document,
the Ada part doesn't need to be recompiled. This needs some bookkeeping,
at least. A piecewise intergration with a VCS seems desirable, and XML
can help here.
 Sounds like quite a bit of work to make such a thing.

A similar technique has used text processor macros to separate source
text from prose and pictures, IIRC.
