(+ 1)

A year or so ago I wanted to create a Collada importer. Collada comes with an XML Schema, so I wanted to automatically make a parser for that. But no tool existed :(

Note that an existing tool from Microsoft failed on the Collada schema  (something with circular references, see link), so Collada might be a good test case :-)

More specifically, I would be interested in the degree the Haskell
community uses XML Schema, and if you were tempted to use it if we had
an implementation. To further expand the question, how useful do you
consider each of these components:
* a validator
* a pretty-printer
* a translator from XML Schema to Haskell, similar to DtdToHaskell[4]
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 parser.
