I. please specify the extent of the prefix binding as well as the scope while the wd is clear that the scope of a prefix-to-uri binding within an element is dynamic, the intended extent of the binding is unclear. the discussion which has appeared on xml-dev, for example, leaves room for the interpretation, that the binding has indefinite extent. a binding which is afforded dynamic extent has a clearly understandable semantics and is readily implemented, since the parser's state is sufficient to implement the "inheritance". it would even be possible to implement it on the basis of "ephemeral" attributes - which a serializer introduced into the stream on the fly as needed and which a non validating parser would be free to discard after application. if the binding is intended to have an indefinite extent, which interpretation some xml-dev discussion might be taken to imply, (see, for example, mr clark's remark on passing state between the parser and the application for the purpose of decoding attribute values: http://www.lists.ic.ac.uk/hypermail/xml-dev/9808/0173.html) then an implementation which retains a defined semantics in the presence of side effects is more difficult (it would appear analogous to the "upward funarg" problem). since the benefit of supporting indefinite binding extent is unclear, i would suspect that dynamic extent would be the better alternative, but ask for clarification. xml-dev: A list for W3C XML Developers.
