exactly this. Its a very minor thing but I think that if we are going to
clarify ths text as suggested in issue 102 then we should make it clear
that the AT commit is simply directing the participants to make their
tentative changes final. Previously the text might have been interpreted
that "tentative" meant "not persistent" and so "commit" meant "make
persistent". For some participants that is exactly what it means but not,
typically, for Volatile2PC participants. And, even for those participants
where commit does result in a tentative change being made persistent, it is
the participant (or a resource manager it delegates to) and not the
coordinator that deals with persisting the data and making it visible.

mm2: We have consistent views then, Ian. Perhaps if we separate the
sentences:

Your proposed text:
"The actions taken by a transaction participant prior to commit are only
tentative (and so typically are neither made persistent nor made visible to
other activities)...Commit directs the participants to make the tentative
actions final so they may, for example, be persisted and made visible to
other transactions.  Abort directs the participants to make the tentative
actions appear as if the actions never happened."

To:
"The actions taken by a transaction participant prior to commit are only
tentative. Typically those actions are neither made persistent nor made
visible to other activities....Commit directs the participants to make the
tentative actions final.  For example, they could then be persisted and
made visible to other transactions.  Abort directs the participants to make
the tentative actions appear as if the actions never happened."
