In XSL, if two elements have the name namespace but different prefixes, they are processed differently (at least, for the XSL namespace itself). This is essential for XSL scripts that generate XSL. This cannot be done if either the prefix is lost or unless some other arrangement (e.g. adding some attribute giving an instance number) is used. Also, prefixes form part of the markup. They should have documentation meaning. I think it is bad if the "rdf": prefix were to be replace by "xyz" or, worse, by some prefix generated at random like "dom". So, like document-entity encoding, prefixes do not form part of the canonical information set of the document but they do form part of the pragmatic information set required for round-tripping. Different instances of the same document are required for programming languages that use XML syntax and which allow namespaced elements as data. Prefix-preservation is required for this. Prefix-preservation is also required for round-tripping. Rick Jelliffe xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
