Haskell badly needs better middleware.  At present that means WS-* 
stuff, which is all defined in XML Schema.  So the Xmls2Haskell 
translator would be a really valuable foundation for that.

Also it would be particularly valuable if the XML Schema parser 
generated a parse tree which was then interpreted by the Haskell 
generator, as that would make it much easier to build other tools (e.g. 
type validators, schema version translators) on top of the XML Schema
