XInclude using multiple-colon urns

Question

Based on How to use xpointer with Xinclude to reference elements ...

I'm having problems including a nested element using xpointer when the urn namespace contains multiple colons.

Test1.xml

<?xml version="1.0" encoding="UTF-8"?> <Root xmlns="urn:some:namespace"> <element1 id="001"> <element2 id="001.1" order="1"> <element3 id="001.1.1"/> </element2> <element2 id="001.2" order="2"> <lement3 id="001.1.2"/> </element2> </element1> </Root> 

Test2.xml

 <?xml version="1.0" encoding="UTF-8"?> <Root> <element1 id="999"> <element2 id="999.1" order="1"> <element3 id="999.1.1"/> </element2> </element1> </Root> 

Merge.xml

 <?xml version="1.0"?> <Root xmlns:xi="http://www.w3.org/2003/XInclude"> <xi:include href="Test1.xml" xpointer="xmlns(ns=urn:some:namespace)xpointer(/ns:Root/ns:element1)" parse="xml" /> <xi:include href="Test2.xml" xpointer="xpointer(//Root/element1)" parse="xml" /> </Root> 

Command:

xmllint --pretty 1 --xinclude Merge.xml

ERROR

 Merge.xml:5: element include: XInclude error : XPointer evaluation failed: #xmlns(ns=urn:some:namespace)xpointer(/ns:Root/ns:element1) Merge.xml:5: element include: XInclude error : could not load Test1.xml, and no fallback was found
