Since the structured element syntax already exists, wouldn't it make more sense for an attribute to _reference_ a hierarchy of attributes, expressed in element syntax, elsewhere in the document? Given your example: > <person age='49'> > <.name> > <.first>Henry</.first> > <.last>Thompson</.last> > <.middle>Swift</.middle> > </.name> > <children otherParent='p33'> > . . . > </children> > </person> I would do it like this: <person> age='49' name-ref='xqz4834'> <children ...> ... </children> </person> ... <names> <name ID='xqz4834'> <first>Henry</first> <last>Thompson></last> <middle>Swift</middle> </name> ... </names> No new syntax required. -Steve Schafer *************************************************************************** This is xml-dev, the mailing list for XML developers.
