Does someone have a fix in mind that could be submitted as an erratum? The
intent was indeed to make the authserv-id either a plain old ASCII domain
name or an A-label which doesn't need quoting. I missed that RFC 6532
didn't update "value", unfortunately.
Unfortunately, 8601's defintion is a mess. At the bottom of page 15 it
says this about authserv-id, which contradicts the ABNF:
Note that in an EAI-formatted message, this identifier may be
expressed in UTF-8.
If you want it to be a domain, the ABNF should say:
authserv-id = domain-name
The text below says domain-name is imported from RFC 6376, which I presume
includes the updates from RFC 8616 that encourage U-labels in EAI
messages.
This is not strictly backward compatible with the current text, but I
don't think I've ever seen an authserv-id which wasn't syntactically a
domain name.
