Hi,

I have a xml file like,
---------
<test>
<content Id="target">
   Hello, World!
</content>
...............
<Reference URI="#target">
</Reference>
</signtest>
-------------

And I parsed it as DOM tree and want to use XPointer( id( "target" ) ) 
to get the content. Because of the absence of DTD, I have to hack the 
DOM with "xmlAddID", which make the XPointer work.  And then, I want to 
make a C14n transform over the DOM, I can not get the correct result. 
What alse must I do in order to get the correct C14n?

  XPointer id() is actually XPath id() and only works if you can assert
IDness of an attribute, and that requires a DTD per the spec. Trying to
make what you suggest would simply make the library not conformant to the
specifications. Sorry that's not possible. Use a different XPointer
expression not based on id().
