Re: [Sdn] I-D Action: draft-xia-sdnrg-service-description-language-02.txt

There appear to be two, separable technical issues in this draft:

1) What information is needed to represent a service request.
2) How to represent and transport the information for a request.

The first part may be a good area.

For the second part, I wonder if there are not already available methods to declare a schema and represent and transport the information governed by it.
It appears the draft is proposing to invent another mechanism.
It would be nice to understand the reasoning behind this choice.
