And therein lies extreme danger.  I, like (one would hope) most XML 
vocabulary designers, specify element names and attribute names that 
are somehow mnemonic to their intended usage.

However, as a document author, not to mention the author of tools 
intended to process XML that uses such a vocabulary, I MUST NOT go by 
intuition to decide how to mark up my document or how to process 
documents.  I MUST know the vocabulary designer's intended meaning or 
I'm likely to screw things up royally.  Element names might be 
"clues", but they are not "proof" of anything.

(For example: Is a book "title" 'the same as' a person's "title"?  Is 
it 'the same as' the "title" to a piece of property -- real estate, 
vehicle, etc.?  Is it always a noun, or sometimes a verb, or even an 
adjective -- when used in those different ways, the structure 
[attributes, children] might be different and the processing is 
almost certainly different.)

Hope this helps,
