Title: Message
I
agree with all the rationale behind the dataweb (per Drummond's earlier mail),
and believe that this example is successful in fulfilling that
vision.
As
passionate as I am about the dataweb vision, I am also passionate that people
MUST NOT change their existing XML in order to achieve that vision. They
MAY want to change it, but they shouldn't be required to change
it.
This
example appears to fulfill the requirements of the Dataweb AND not require that
folks change their XML.
I've
seen how hard people fight against something that doesn't look familiar, and
something that makes them change their data structures.
If we
can fulfill the goals of the dataweb in a familiar, un-obtrusive manner, why
choose any other way?

What this says, in effect is, the we wish the XML in the data section
looked like this
