Either way, as long as they are near the beginning of the doc.
Things can get confusing if there is a <title> for the document
and also <title> elements in a bibliography.

We could also represent the entire ingredients list in RDF, but what 
would it buy? My suggestion is to use standard representations
for *common* metadata. Parts of the data model specific to recipies
probably should be represented with specific structure.

Now, it sure wouldn't hurt to put things in <subject> elements 
like "vegetarian", "vegan", "low-fat", "kosher-dairy", "cookies",
"kids cooking", etc. Off the top of my head, I'd start with the
Library of Congress categories under TX643 to TX840 (Cookery).

Of course, then someone will want to find wheat-free recipies or 
anything containing both chocolate and garlic, which is why we 
still have full-text search ...

Hmm, this is an interesting sample case for search, too. Maybe I can
use this to demonstrate the advanced XML support in our next release.
