This is what we do. The CMS generates XHTML/JSPs putting together 
everything except what needs to be dynamic. For runtime the JSPs get 
precompiled. At runtime we use a servlet filter that wraps the response 
before hitting the XHTML/JSP (the JSPs generate XHTML). After hitting 
the page a simple transformation renders the output stream back to the 
client. We use the XSL to get valid XHTML output that plays well in all 
browsers (clients *are* asking for XHTML).

The transformation is basically an identity transform with a few basic 
parameters passed in, for example the user name and the user's current 
L&F. This way, many pages that would have to be dynamic can be simple, 
well-formed HTML. We use Caucho's Resin servlet container -- it has a 
compiling XSL processor which transforms very fast (you can probably do 
the same thing with Tomcat and Xalan's XSLTC). I suppose this type of 
transformation can be done with STX, but we have not had any performance 
problems.

best,
