xinclude xpointer not including with id

Some background I am using xsltproc to process modular documents to pdf. 

I have a file where I just want the one element included. 

It is not getting included and I am getting error messages, like:

 element include: XInclude error : could not load Version.xml

 

I would think it would be a xsltproc issue, but I am following the examples in the documentation and it is not working like that... so perhaps there is something obvious here I am overlooking. 

 

so file Version.xml contains :

 

<chapter>

  <chapterinfo>

    <date id="DateVer">January 2012 Version 1.2.3</date>

    <releaseinfo id="RelInfo">12-002009-16.c</releaseinfo>

    <copyright id="Copyright">

      <year>2012. All rights reserved</year>

    </copyright>

  </chapterinfo>...

 

 

In my file Book.xml 

I am tring to include the date info... 

<!--Original xinclude should have worked per example in chapter 23-->

<!--xi:include href="" xpointer="DateVer"

                xmlns:xi="http://www.w3.org/2001/XInclude" / -->

 

<!--according to doc this way should also too, but does not-->

<xi:include href="" xpointer="xpointer(id('DateVer'))"

                xmlns:xi="http://www.w3.org/2001/XInclude" />

 

I have also tried :

<!--xi:include href="" xpointer="element(DateVer)"

                xmlns:xi="http://www.w3.org/2003/XInclude" / -->

and 

<!--xi:include href="" xpointer="element(date)"

                xmlns:xi="http://www.w3.org/2003/XInclude" / -->

 

 

and none of these work, I am only interested in including the content of the <date> element from the Version.xml file. 

Now were I to do, this, 

 <xi:include href="" xpointer="element(/1)"

                xmlns:xi="http://www.w3.org/2001/XInclude" />

 

then I get the entire contents from the Version.xml, which is not what I am interested in.

Is there something that I am missing here?

Why is this not working as indicated? Any suggestions?

 

Thanks,
