Peter,

Does this proposal apply to all instances of those words? Note for
example that the PW Status from RFC4446 and RFC4447 uses "Fault", and
the document should probably keep referring to the same terms.

Also, does this comment apply also to the vccv-bfd document? Grepping,
vccv-bfd uses "Fault Detection" and "Fault Status" in all its
definitions (and uses "defect" in one paragraph).

Finally, is is a better disposition to use the text from
draft-ietf-pwe3-oam-msg-map-09 in the definitions/terminology section?
Quote:

   The words "defect" and "fault" are used inter-changeably to mean a
   condition which causes user packets not to be forwarded between the
   CE endpoints of the PW service.

Thanks,
