Curious, does the common XML source look something like XSet's production
rule language [1]. Looking at the RELAXNGCC parser generator respiked my
interest in using XSLT to generate things like JavaCC grammars.

Indeed to the extent that an XML 'complex type' is essentially a regular XML
expressions, and that simple types are essentially regular string
expressions, I've thought it would be interesting to further develop the
XML/EBNF stuff so that it might be suitable for expressing attribute 'types'
and subtypes of element PCDATA, etc.
