Expanding the XPath support for XPOinter xpointer() scheme

[Sanjaya Liyanage]

Hi all,
     After I completed the GSoc project "*Implementing a streamable subset
for XPointer xpointer() scheme for XInclude*" now I'm trying to expand the
XPath support for XPointer xpointer() scheme as currently it supports for
very limited subset of XPath.I will begin from adding the predicates
support.let me know any suggestions.

Thank you.
