Re: Character Entities: An XML Core WG View
>XML core would be a natural lead group for such an activity, don't you >think? (I'm speaking here in a personal capacity, not as a representative of the Core WG.) I think the natural group to lead - or at least start - such an activity would be the people who need the functionality. There are two problems: (1) People keep coming to us saying "something has got to be done about character entities". When we have asked why, we have received various different answers, some of which are based on factual misunderstandings, such as that entities can't be used with Schemas. Others, while not wrong, do not seem (to me) to justify the cost of a new mechanism, such as that the XML spec does not require processors to read an external subset. The document just published aims to make the WG's position clear, so that if there really is a need for a new entity mechanism then those who need it can make a coherent case for it without rehashing the same issues over and over again. (2) There are (as far as I know) no readily-available experimental replacement mechanisms for those who believe they need them to try out. I don't think the Core WG should invent and standardise a new mechanism. If there is to be a new mechanism, it should be proposed and implemented by others and then the Core WG can, if necessary, produce a spec for it. Otherwise we will have the usual outrage from those who think that the W3C is a great conspiracy to make everything more complicated. Perhaps the constituencies who believe they need a new mechanism (XHTML? MathML?) should form some kind of ad hoc working group to produce a requirements document. -- Richard
