I agree it is not trivial to implement a full XML parser, but the experience
of a novice individual is irrelevant.
The Full XML 1.0 recommendation, complex as it is, does not appear to be
acting as a barrier to entry for serious tool vendors.

I believe that XML 1.0 needs to be treated as a de-facto standard.  This is
the only way to
(a) achieve the kind of interoperability that the industry is seeking
(b) avoid undermining the other technology that is being built on top of it.
It is only because XML 1.0 has remained stable for a while now that other
"standards" (such as xhtml) can be created.   I for one am grateful that
most vendors seem to agree with this premise and put a lot of effort into
achieving (and boasting about) conformance.
