Separate attribute events raises a question.
Unlike SGML, XML does not specify that the order in which attribute values
are supplied in a start-tag is insignificant to applications.
(Perhaps I missed something it in the spec.?). A processor working
sans DTD obviously cannot determine a declaration order in which to generate
Annex G of the SGML handbook just says the order is insignificant. However,
nsgmls ESIS supplies then in declaration order and I for one have written
apps that relied on that. Perhaps writing apps that rely on a specific
order of attribute event arrival is just plain bad design!
Anyway, the dictionary approach, supplying all the attributes in one go
side-steps buffering and state space for simple little SAX apps. that want
up attributes X and Y of element Z and nothing else.
While on this subject, what comes first, a start-tag event or its attribute
