It's not quite identical. The XSLT language specification defines which 
prefixes are in scope within XSLT and which aren't. XPath leaves it to 
the host environment, which means for example that XML Spy and Stylus 
Studio can legitimately have different rules at the XPath level but not 
at the XSLT level.
