Erik Meijer and Mark Shields are working on a system called
XMLambda, which includes a Haskell-like type system for
XML documents.  I've only seen one paper on it so far [1],
and it doesn't go into much detail about the type system
or inference algorithm, but it looks somewhat promising.
Don't know how much, if any, of this would apply to XSLT 
though...

    Manipulating XML Documents.  <URL: http://www.cse.ogi.edu/~mbs/ >,
