Saxon XSLT and XQuery Processor

The identity transformer (invoked from JAXP when no
stylesheet is specified), when used with a
StreamSource, doesn't set namespace processing options
on the SAX2 parser. It shouldn't need to, because the
options it requires are those specified as the
defaults in SAX2. However, it appears that the APache
Crimson parser doesn't do namespace processing unless
explicitly requested, which has the effect that
element names are lost in this transformation.
