Impact of the usage of unique identifier as URN into XML document s ?

To: "'xmlschema-dev@w3.org'" <xmlschema-dev@w3.org>

In the context of our applications, we have choose to use URN as the
standard form of our generated documents identifier. Here is an example:

<document id="urn:hsc:EFECD0FF-C0A8021C08DEE071-D030940E">

This form is not compatible with ID/IDREF type provided by XML schema but is
compatible with key/keyref mechanism. In the context of our schema we
defined it as follow:

<xs:key name="DocIdentifier">
  <xs:selector xpath="."/> 
  <xs:field xpath="@id"/>

It works fine, but I don't know the future impacts/limitation of such
choice, specially concerning the usage of URN as unique identifier in
conjunction with others XML technologies. Does anybody have any comments,
suggestions or best practices about this subject? Can you see future

Thanks for your answer
