Please describe the problem:
After clonning a subtree (using xmlCopyNode internally) the clonned  
XML_XINCLUDE_START (very useful BTW) nodes do not carry their 
original attributes (such as href and xpointer). A suggested patch is in the "other info" section.

Steps to reproduce:
1. parse a file with <foo><xi:xinclude ...></foo>
2. use xmlCopyNode on <foo/>
3. examine the properties of the XML_XINCLUDE_START node in the copied subtree


Actual results:


Expected results:


Does this happen every time?
