Well, I could not find where the spec require the validation of the provided GID field for
ServiceRecords. The fact we allow non valid or unknown GIDs to be registered might become useful.

As I said - I did not see anywhere in the spec a specific requirement for that.
Why do you see this as an issue?

This is a big hole! Thanks for bringing it up. I think we should enhance the
SA client code to recognize this and re-issue the MAD. Can this be done in the
lowest possible layer?
