I always thought that attributes listed in GSS_Inquire_name() wouldn't
block: because they are would be "raw" things in Kerberos
authorization-data or similar.

Also, have you seen draft-williams-kitten-generic-naming-attributes-02 ?

That I-D uses your idea of attribute name prefixing to control a variety
of things.  It makes blocking/non-blocking attribute-specific for some
attribute prefixes.  In particular it adds a generic attribute prefix to
indicate the application's desire to not block.  I think this is the
right approach, and I think it was your idea.
