That the charter is "clear in its description" is sadly not a widespread view. This is why several of us are trying to get the terms defined in order to add the missing clarity. Note that this confusion is present despite the very extensive OGP background within the group. For new readers of the charter, its meaning will be even less clear, if not completely obscure. In the absense of this understanding, it is not possible to say that the document "accurately describes the scope of what we want to do", since we don't know what it describes. The scope is currently unknown to a significant number of participants. As the charter is clear to you, perhaps you could assist in the process of clarification by answering some of the recent questions made to the list? I am sure that this would be widely appreciated.
