If I understand you correctly, in the header I'll have something like
<xptr url="foo-url" id="foo"/>
while in the text using
<rs type="url" key="foo" from="id(...)">
This seems all right. The 'from="id(...)"' is not the most beautiful of
markup constructs, but we'll need something with its functionality to
achieve the purpose of defining the url only once but using it repeatedly.
The header information I would like to XInclude, or something to that
effect, to be able to reuse it in all of our files.
