OTS11 — Forcing child activities of completed parents to fail is too restrictive

Section 2.2.9 of the specification, in the description of the compete
method, includes the following text:
"If the completion status is CompletionStatusFail, or
CompletionStatusFailOnly,
any encompassed active or suspended Activities will then have their
completion status set
to CompletionStatusFailOnly and transactions will be marked rollback_only."

This behaviour is too restrictive for extended transaction models that may
wish to allow child
activities to complete successfully despite the fact that a parent activity
is failed. I suggest that
this restriction be removed.
