I didn't review the code very closely, but at first sight it looks
like you have a couple of unrelated and whitespace only changes that
should probably be in separate patches. I think there are also e.g.
some comments that should be updated / removed. I can try to answer
some of the questions, but ultimately it's up to Alexandre.

Seems fine to me. Although it's a bit annoying that Khronos doesn't
seem to want to make any guarantees about the stability of the XML
format.

I think so, but I also think it's common to just put things like "use
XML::Simple;" at the top of the file.

Not initially, but we may want to in the future.

For mapping type. E.g. in gl.spec, ClearColor() takes 4 parameters of
"ColorF", which is mapped to GLfloat in gl.tm. In the XML files that
information is available as the "group" attribute, but we don't need
it for our purposes. (See also
