To add new datatypes or syntax is relatively straightforward. And I'm not doing the whole lot, either - just the commonest ones.

IMO that was nearly a no-brainer and orthogonal to any other effort - it would have helped other activities since. And the arguments are unlikely to stray beyond what the precise definition of some weird type is... I can live without min and max in that spec if it helps. >>I note that max and min have changed from being content to attributes. > >No! Read the early part of the spec. Per RDF, these things are >*properties*, which can be given either as elements or attributes. I admit I haven't given it very much detailed attention. But given that there are ElementDefs and AttributeDefs and that the latter produce attributes... But I will read it more carefully.
