I thought that the text in Appendix A could be clearer, and also would be more useful in the introduction. I propose 
that we remove Appendix A, and place the following text at the end of the Introduction, which also provides a useful 
summary of the Appendices.

We define in Appendices A-D normative XSD and WSDL for BES-Management
and BES-Factory, respectively, and in Appendices E and F non-normative
examples for the two interfaces. 

Recall that the OGF OGSA WG has defined the notion of a Base Profile:
a specification that places certain constraints on how resource
modeling specifications such as the WSRF or WS-Transfer families
should be used in any OGSA-compliant specification. At the time of
writing, only an OGSA WSRF Base Profile [OGSA WSRF BP] has been
defined, but others will presumably be produced in the future.

We have sought to define a BES specification that while not, in
itself, compliant with any OGSA Base Profile, can be composed with
appropriate other port-types to produce a BES that is compliant with
any specific OGSA Base Profile. To illustrate how this composition can
be achieved, we explain in the (non-normative) Appendix H how an
implementor can construct a BES that is compliant with the OGSA WSRF
Base Profile.
