That's because Xalan doesn't implement XSLT 2.0. I would expect it to give
you an error message when you use the xsl:namespace instruction.

They don't work together. As I think I said, xsl:namespace-alias only
affects the results of literal result elements.

cxsl:stylesheet is a literal result element. When an LRE is evaluated, all
its in-scope namespaces (other than those listed in exclude-result-prefixes)
are copied to the result tree.

Because that's the way it's specified.

My only surprise here is that Xalan doesn't error on this stylesheet. The
rule is that an XSLT 1.0 processor, given a stylesheet that says
version="2.0", should give a run-time error if you try to execute an
instruction in the XSLT namespace that hasn't been defined in the XSLT 1.0
specification, unless it has an xsl:fallback child element.
