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.
