I can think of other uses, eg change an xpath that queries docbook4 (in
no namespace) to one that queries docbook5 (in a namespace) by prefixing
the appropriate names. (although in many cases this might be better
achieved by just resetting the default xpath namespace)

In the xq2xml distribution I have a stylehseet that re-writes any xquery
(or xpath) that uses the optional axes of xquery into equivalent
expressions that do not use those axes, etc....

Currently xq2xml uses an extension function to use a java xquery parser,
I wonder how much work it would be to make it all pure xslt.....
