I've run into a "Variable accessed before it is bound!" exception. This occurs on a current build from CVS. Attached is a test case. As far as I can tell this is permissible XSL, besides, it worked OK on xalan-j-2_0_1. From my debugging so far it has something to do with the VariableStack getting out of sync and/or lazy evaluation failing for the apply-templates as the content of a with-param. Hopefully I'll be able to debug it and describe a fix. If someone else is working on it, I'd be happy to work around it because I'm also trying solve a transformer reuse problem.
