Using xerces-c XInclude with absolute paths
===

I want to include another xml file using the xerces-c XInclude functionality with an absolute path and/or a relative path. However, if I do something like

    <xs:include href="<some-absolute-path>/foo.xml" />

And this file (say bar.xml) is located at <some-location-path> then I get the following error:- 

    Warning at file file:///apps/ttech-waltham/owagh/test/b.xml, line 0, char 0
      Message: unable to include resource 'file://<some-location-path>/<some-absolute-path>/foo.xml'

Any idea on how I can specify this? I want to be able to do both, give relative as well as absolute paths in href.
