Re: (PFWG) ACTION-211 Query re: SVG Request for @order for Access Module

I appreciate what you are trying to accomplish, and I will leave that 
suggestion to the working group.  I have a strong bias against 
encouraging the behavior your are trying to permit.  This is an XML 
module, and XML does not permit duplicate IDs.  Period.  It would be 
inappropriate to use this module as written in any non-XML grammar.  And 
even in such a grammar (e.g. HTML4) duplicate IDs are not permitted.  So 
I don't see why defining the behavior and therefore encouraging people 
to violate the rules is a good idea.  If it were up to me, I would 
codify that duplicate IDs are an error, and that the behavior of an 
implementation in the face of them is unspecified (formal, IEEE term... 
means its a bad idea, don't do it.  won't work portably).

But, like I said, I value your input and know that I am dogmatic in this 
respect.  So I will leave it to the working group.
