I think there may be another useful distinction between
camps in the XML world besides the well-known "document"
vs. "data" one.  I think Walter, Simon, and others
belong to a "publishing" group that stands in contrast to
the "messaging" group.

In a publishing model, as we observe on the Web,
there is little opportunity for the creator of a document
to negotiate with its recipient.  As a result, fewer,
more fundamental, more syntactic agreements are required
to achieve interoperability.

In a messaging model, the creator and receiver of a
document have the opportunity to negotiate prior
agreements such as schemata, use of binary serializations,
particular APIs, etc. in order to produce more efficient

Systems that rely on accessing "publish"-style data,
like Walter's and Google, are hopelessly lost when faced
with "message"-style data, since they cannot be parties
to all the necessary agreements.  That is how currently
working integrations can be harmed by the proposed
suggestions, unless they are used in a true messaging
context internal to a system and never leaked to the
outside world, or even the remainder of the enterprise.
