[xml] schemas

["T.J. Mather" <tjmather tjmather com>]

I'm interested in adding support for XML Schema to libxml.  I was 
wondering if such a contribution would be welcome, given the API freeze.  

I was thinking that it would be neat to develop a Multi-Schema XML 
validator, much like Sun's Multi-Schema XML Validator[1].  We could build 
support for XML Schema at first, then add support for RELAX NG.  This 
shouldn't be too hard, if we take care separate the XML Schema datatypes
from the rest of the Schema implementation, since RELAX NG can support XML 
Schema datatypes.
