 Chris, Awesome. You have about cracked the namespace conundrum. Part of the key is to see that the XSLT is also an XML document and follows all the same rules as any other XML document as to its namespaces. So: > Why would the XSLT serializer write explicit namespace references that arenbt needed by context? In this case, all the declarations in samples you have shown are needed with the exception of the stray binding to an 'mml' prefix, which you removed. They would not be needed if the processor (say) assigned all its own prefixes to names, instead of using the names as given in the XSLT. But we would hate that. So it does its best to give us what we need, with the names it thinks we want. > Isnbt the point of namespaces that everything is fully qualified internally, then the output can adjust accordingly? Yes! As you've discovered, that can require some jiggery when multiple vocabularies are competing for unprefixed names (or the same prefixes). > How do I get a clean <math> island of MathML content without namespace stuff cluttering up its contents? Bravo! Actually with a little practice you can make it so your code is reasonably clean even in mixed-namespace use cases. Old project: https://github.com/wendellpiez/XMLNamespaceFixup (but if you do things right you'll never need it).
