proposed Executive Summary paragraph

Hi,
in today's metamodel meeting today I promised to add some verbiage to the
executive summary of the specification schema document:

Here's a proposed new version, please comment:

Executive Summary:

The ebXML Specification Schema is a logical subset of the metamodel behind UMM
as specified by UN/CEFACT TMWG's N90.

The ebXML Specification Schema provides for the nominal set of specification
elements necessary to configure a runtime system in order to execute a set of
ebXML business transactions. The current version of the specification schema
facilitates the infrastructure release of ebXML's TRP, TP, and RegRep
specifications. A subsequent version will address additional features such as
(but not limited to), Resources/Events/Agents, multi-party coreography,
Context based content.
