Section 2.4.2 says:
[[ first bullet on page 14: ]] o If a DNS request to resolve the host name in the request URL returns a response that indicates that no matching result is | available (NXDOMAIN), the UA MUST remove that request URL from the list of alternatives for the Configuration Service Domain.
It should say:
o If a DNS request to resolve the host name in the request URL returns a response that indicates that no matching result is | available, the UA MUST remove that request URL from the list of alternatives for the Configuration Service Domain.
Notes:
Rationale:
See the related Errata Note for Section 2.3.1.2 (EID=2622) for
background and details. Dropping the parenthetical "NXDOMAIN"
here seems to be the most simple way to remove the misleading
allusion that "no matching data available" be equivalent to a
NXDomain response.
