Hi,

I have just seen this pattern

   import ietf-inet-types {
     prefix "inet";
     reference "RFC 6991";
   }

and I wonder how people understand this. From the way this import
works, any (newer) version of ietf-inet-types is OK to use to resolve
the import but I could see that this statement makes people believe
they have to use the version of ietf-inet-types contained in RFC 6991
(but then this should have been import by revision). I know that we
had a common practice to have comments before this was possible, like

   import ietf-inet-types {             // RFC 6991
     prefix "inet";
   }

but then this was a comment, now the RFC numbers becomes part of the
definition. Should we be concerned about this? Or should we suggest
to be more clear about this, e.g.:

   import ietf-inet-types {
     prefix "inet";
     reference "RFC 6991 (at the time of this writing)";
   }

/js
