[plt-scheme] xexprs and sxml

The state of PLT Scheme's support for XML is still a little 
unsatisfying; it's possible to use either xexprs or SXML but certain 
tools require one or the other. If I want to perform some XML 
transformations to generate pages for the web-server, it seems awfully 
uncivilized to use SXSLT to create SXML, then marshall to XML, 
unmarshall back to xexprs and send to the web-server which will just 
convert right back to XML.

Is there a plan to move away from xexprs? That'd be a shame, because I 
like xexprs. I suppose tools like WebIt! and SXSLT could be made 
abstract in the data representation, but that might be a little 
over-engineered. Is it better just to write a SXML->xexpr and 
xexpr->SXML library?
