Re: DTD Notation raises a question

[Rod Davison <rdavison@sprint.ca>]

Not in the spirit I was speaking.  It is generally accepted that synonyms are 
not the same as different references for the same entitiy.  Thus "The 
President of the United States" and "George W. Bush" are not synoyms but 
different ways of referring to the same thing.

Synonomy is a matter of semantic meaning not reference.  In my example 
"middle" and "medial" are considered synomous based ontheir meaning, not on a 
reference.

I didn't raise this though as a theoretical nit-picky point.  I was thinking 
of the problem of given wo content models, asking what makes them equivalent? 
 What makes them synonymous?  Clearly at one level, they are equivlent if and 
only if they produce exactly the same set of "sentences".  what I was trying 
to ask, perhaps poorly, is that given a content model A, can we apply a set 
of transformations to it (e.g. adding "redundent" paraentheses) to produce a 
differnt content model B with the assurances that the models are equivalent.

Thanks
