I have looked through the radext mailings and saw
some discussion but could not find anything specifically regarding the
reason for preferring suffix over prefix in determining the routable realm.
 I understand it is too late to change anything when in last call
so just for my edification, is it because it was agreed to preserve the
designation of the suffix as "the realm" from the original RFC?
  It is actually standard practice with all the large roaming aggregators
with which we partner to use the prefix domain as priority over the suffix
when both exist in the string.  Not blaming anyone or group but it
is unfortunate that since there was nothing in the original RFC with regards
to chaining domains that a practice developed that is non-compliant.  I
understand not wanting to define the '/' since it would break the original
RFC but unfortunately those roaming partners all use it for the prefix
delimiter as well.   I guess it is fairly common these days to have
a standard practice that does not comply with the standard and that's life...

Best regards,
Josh
