6<!--
7The following stylesheet puts out <out>abcabc</out>, which is absolutely
8incorrect.  If you uncomment the commented value-of and variable, it results
9"Variable accessed before it is bound!" error message.  The bug seems to be
10related to the inner call-template... it looks like something in the stack
11frame is not being restored???
