Dan:
Thanks for pointing out the relevant use case. I was just trying to
find out if there is a need to augment the CPA with user and
password information to allow basic authentication to be performed.
Do you think the 1.1 MSG and CPP/A specs need to be aligned
with respect to the issue of basic authentication?
Regards,
