After reviewing the first document and in lack of more input to the group the decision was to focus on the second document. The discussion started with a kind of reality check. The original question was, what can be archieved through such a document. The users need something to point to. Leading the way to best current practise is a good description for the purpose of this document.
Users have to deal with a highly hierarchical system of vendor, seller and reseller.
The users will need a document in simple language, so that everybody can understand it and use it. There is a special situation outside the US, where even the vendor, seller and reseller have no access to the technical information and the detailed knowledge. For example, it is a wrong assumption that every party has access to source code. The producers are the audience, but users will read it. This will lead to the use of the document to in some ways force the technology producer to a specific behavior.
