Subject: Issue 7 update
Peter, Doug, and BTP group, Attached are the updates to the informal XML section of the spec and the schema that resulted from the issue 7 discussion. The following comment made by Doug during the discussion is not resolved in the attached documents... > The superior-type element has a default of "atom" but that is not even > indicated in text after the table. The transaction-type element in a > BEGIN should be used to set the superior-type of the created CONTEXT > but does not have a default. These elements are pretty much Booleans > (have very similar behaviour to an is-cohesion Boolean with a default > of false) and I can see the utility of providing that default. Again, > the smaller change would be to remove one sentence (at lines > 2175-2176). I cannot remember if the protocol provides another > in-band mechanism to create a CONTEXT beyond BEGIN (without an > associated CONTEXT, of course). If such a mechanism exists, other > choices may be prudent. We did not discuss this issue on the call. According to the current state of the docs, the CONTEXT's transaction-type has a default, but BEGIN's transaction-type does not. Regards, Alex
