Unique values in XML documents

Hi All,

I have a series of XML documents. I want to ensure that when any of these
documents
contains the following element:

<id></id>

That the value supplied is unique across all <id> elements contained in all
the documents.
I know i can enforce uniqueness of values in a single document by using the
<unique>
structure in XML Schema. Does anybody know how to do this across multiple
documents?

Thanks
Mat
