  Sorry, that's not XPath behaviour, and not possible with libxml2 which
implements XPath. I'm very surprized that such a deviation from a W3C
standard was allowed in an IETF specification, there used to be liaison
between W3C and IETF to avoid this kind of problems. I note that RFC 4825
references an XPath 2.0 Candidate Recommendation, libxml2 implements
XPath 1.0 , so maybe the divergence is normal but this should be
double-checked. I also see it reference XML Fragment Interchange CR
draft, so I really wonder if the liaison work was properly done on
that IETF specification >:->
