That's ok David - after all, brevity is the soul of wit, as the bard put 
it.  Still it is the case that MarkLogic's built-in term indexes (not 
the range ones) are based on element (and attribute) names, and although 
there are also contextual (parent/child) indexes, you will not get best 
performance there if you rely on context sensitivity; eg queries for 
//name can be resolved straight out of the indexes accurately and don't 
require additional filtering, wheras //person/name and //place/name 
require (some) extra processing.  For example, to get an accurate count 
there, ML has to filter every possible result returned by the indexes.  
ML is spiffy and does this really fast, so you usually don't notice, but 
if you have 1M docs and want to know exactly how many have a person name 
"Lee", you really will notice the difference.

I'm not trying to run down MarkLogic - it's a great system for XML work; 
merely pointing out that in some cases practical considerations that 
have little to do with semantic correctness may inform the design of 
your tag set.
