Sorry to reply to my own message, but I caught an error:

"As a general rule, the more specific the pattern, the higher its 
priority."

A misperception on my part. Rules with context (something more than just 
the element name) get a priority of .5, regardless of how specific the 
context is.

Sorry about the misinformation in the earlier post.
