I don't see that this misses the point. We want a specific set of output from
our source document. With DocBook, you write something to parse the source
directly, and produce your output. With (La)TeX you write a tool to use
(La)Tex to parse the source, and produce your document --- look at the
difference between TeXinfo and LaTeX documents, for example; they both use the
same backend (TeX), but the sources are quite different. Similarly, you can
produce HTML, XML, RTF, PostScript and PDF from the same LaTeX source with
little hassle.

IOW, both DocBook and (La)TeX can be used to write documents that can be
transformed into whatever output you require, but the techniques are
different.

I had forgotten that DocBook comes in an SGML form as well as the newer XML
form. However, SGML is *lots* harder to parse than XML, so using SGML DocBook
loses some of its benefits.

Yes; whatever tool we use, it needs to be easy to write the documentation.
