[SR-Users] Does xcap server of kamailio support partial update of xcap document?

[Daniel-Constantin Mierla]

Hello,

inserting a new node seems not to be possible through xpath operations 
only, so I made a patch to be able to add new nodes (entries) -- see it 
attached -- it is for devel version (master branch), hopefully it 
applies clean to 3.1 if you are using that version.

There was no option to test it at all, I just made sure it compiles. Let 
me know the results, if it runs but fails, send me the output with 
debug=4. If all is ok, I will commit to git repository.

Cheers,
Daniel
