Nope. To do that, you need an XQL-like engine or a repository.
We're aimed at the other 99% of the market.

Also, when I was researching published DTDs, nearly all of them 
qualified the sub-elements or used entirely different names, so 
that context wasn't necessary: <docAuthor>, <bibAuthor>, <byline>, 
whatever. The only tag that was occasionally reused in different 
contexts was <title>. There is a heuristic (hack?) to use the 
first occurance as the title for the results page. A better 
solution than expecting customers to know XPath, then trying
to teach them over the phone.

Our house style is to err on the side of simplicity and ease of 
use, because it almost impossible to remove features, even if they
confuse almost everyone and benefit almost no one.

I actually spent more time making sure that sentences were extracted
properly from things like this (with multiple mappings possible):

   <title>The <hi type="italic">Ghastly</hi> Happenings at 
      <event><trademark>Infoseek</trademark>'s Halloween

I've got nothing against complex searches, but they don't benefit
our users. In the internet search world, people who type two-word
queries are power users. Really.
