Does anyone have an example of a collision that can only be solved, or even best be solved with XML Namespaces? A neccessary condition is ideal, but examples where namespace represents an optimal design decision will do. I'm asking for two reasons: - in my work with XML I've never run across a collision problem that seemed to require namespaces. I wondering whether they're rare or whether the markup I dela with is unusual. - I'm looking for markup that I can use for test cases and thinking about the matter. I went looking in the Namepsaces spec and found this example and an assertion: [[[ <section><title>Book-Signing Event</title> <signing> <author title="Mr" name="Vikram Seth" /> <book title="A Suitable Boy" price="$22.95" /></signing> <signing> <author title="Dr" name="Oliver Sacks" /> <book title="The Island of the Color-Blind" price="$12.95" /></signing> </section> In this example, there are three occurrences of the name title within markup, and the name alone clearly provides insufficient information to allow correct processing by a software module ]]] It demonstrates no such thing to me. For example, here is the sufficient information: /section/title /section/signing/author@title /section/signing/book@title I suspect this particular assertion about the insufficiency of traditional namespaces in the spec is false. I believe for it to be true, there would need to exist markup for which no keys could be computed to dilineate one element or attribute from another. Bill de hÓra
