Med, Thanks for the swift response to my review. See my one reply inline. Kind regards, -Peter >>Page 13, 1st paragraph, 3rd sentence: what's meant here is if any PCP >>error other than a short-lifetime error, or in the case of a failed >>resend, any PCP error at all. The wording makes it seem like the >>short-lifetime errors are somehow not PCP errors and is therefore >>confusing. It also doesn't explicitly deal with how many repeats should be done on a resend. >[Med] The basic behavior is to relay the received error to the UPnP CP. For the short-lifetime errors, the IWF may decide to resend the request and not relay those errors immediately to the UPnP CP. The number of repeats is not specified here as it can be implementation-specific. Your explanation is fine. I just found the wording "If a PCP error response is received" to sound ambiguously as if the short-lifetime errors were not a subset of PCP errors.
