Data Types (was: RE: Dates in XML)

WebBroker uses the datatypes defined in XML-Data. The dt attribute from
XML-Data namespace is used for datatype recognition by XML-Data aware
processors. Otherwise a NOTATION attribute is used for xml 1.0
processors. This is very limited but did what I needed.

Limitations of this trick include:
Attributes cannot be datatyped. 
Extensibility is not addressed.
Encoding (NOTATION) and data-typing should be explicitly seperate
attributes which they are not in WebBroker.

I would not use the WebBroker tricks as is to solve general purpose
problems besides the "RPC" stuff it was designed for. I was able to get
a lot done using only primitive data typing  without the higher powered
features of schemas.
