RE: description of recovery mechanisms

[julian_satran@il.ibm.com]

Marjorie,

Examples is one concrete item that I can understand is missing.
And I will try to provide examples (or complete scenarios) in pseudocode in
06

Over specify - I think that is very bad.

Recovery can't result in too many interoperability issues since the number
of active elements we have for recovery is limited and the actions one has
to follow when issuing or receiving those are simple.

More than just a description is necessary.  I believe the proliferation of
options regarding recovery will make for an interoperability nightmare
similar to early iterations of Fibre Channel protocols.  Too many options
and too much ambiguity result in too many conflicting interpretations.  We
need to simplify, remove options, over specify with examples.
