This is essentially the same solution as used in Ultraseek
Server. The "XML Mappings" page in Ultraseek Server is a
bit simpler, because we didn't want to restrict our customers
to "people who can write XPath expressions". We can map from
an element name, or an element name restricted to an attribute
with a particular value. This handles cases like <abstract>
and <div1 type="abstract">, which is a huge subset of 
real-world DTDs.

I think of them as "meta data elements", using the Dublin
Core terminology, but the model is the same. Quick, call
it a Design Pattern and let's publish a book.
