Putting aside the issue of plain text versus XML file formats for a
moment, can an example of the XML format be supplied ? What are the tags
used and their relationships ? I don't think there's been a discussion
on this yet.

Also, why were lex and yacc chosen to be used rather than some open
source XML parser (already written in C) ?

I also have some questions about the patches but I'll wait to see more
of the bigger picture here.
