It doesn't work in attribute values, though -- href="http://&content-server;/&docroot;/Introduction" This sort of approach (using element syntax for replaceable content) has been discussed before, and has been deployed in environments ranging from semiconductor data sheets to transcriptions of historical texts. If it hasn't caught on everywhere, I think it's largely because of problems with attribute values. You are more likely to want <constant name="amp" /> or <constant name="companyName" /> in practice -- i.e. not just a character, and perhaps even containing embedded markup. But then you sometimes want to strip out the markup, so you end up with multiple defintions or with something like <constant name="companyName" format="plain" /> The contribution of namespaces here is perhaps that schema writers could incorporate the namespace more easily, although it also may make life harder for DtD writers.
