The problem is that XSLT is not a true XML language: the XPath literals
are not broken up into a tree structure. So in order to transform XSLT 1.0
it will be almost essential to delegate the XPath parse to some Java code.

If there was a standard XML tree representation of an XPath, which could
come in useful for all sorts of other purposes, the fn:xpath-to-tree()
function would return it enabling proper XSLT analyses. The reverse
fn:tree-to-xpath() is just a pretty printer.

Given fn:xpath-to-tree(), it would be possible to convert XSLT 1.0 to 2.0,
and perhaps this conversion should accompany the standard.
