[XML-SIG] New version of xmlproc released

[Lars Marius Garshol]

I've now released version 0.50 of xmlproc with a number of improvements:

 - content model validation has been completely rewritten, removing some
   serious bugs
 - there is now support for SGML Open Catalog files and XCatalog 0.1 catalogs
 - some slight speed improvements
 - even better conformance to the specification in some rarely-used areas
 - documentation of interfaces
 - some API changes (new versions of the SAX drivers are bundled with the
   program)

_All_ comments and feedback on bugs, wanted features, opinions etc are most
welcome and really needed. Thanks a lot to everyone who sent bug reports or
encouragement.
