I have demonstrated that by interning names in their namespaces, SAX doesn't have to decide whether names are strings or first class objects. SAX can allow parsers to use any representation they like for names, as long as they maintain that equal names are identical if they are in the same namespace. I think SAX2 should add an interface for names similar to what is described by James, but leave the actual representation to the implementation. SAX2 may leave a footnote that suggests (without requiring) a string representation of names for backward compatability with SAX1 and easy of use for those that don't understand the implications of namespaces. -- Terje <terje@i...> | Media Design in*Progress Software for Mac Web Professionals at <http://www.in-progress.com> Take advantage of XML with Emile, the first XML editor for Mac!
