The aspiration is that XSLT 2.0 should be schema-aware in some sense, though
I don't think anyone knows exactly what this means. But one possible
implication is that functions should be in some sense polymorphic: there are
already core functions whose behavior depends on the data types of the
arguments, and it is desirable that user-written functions should also have
this property. This isn't the case for the current <saxon:function>.
