Re: [netmod] WGLC on draft-ietf-netmod-rfc6991-bis-11

Hi,

You didn't answer my first question about what we actually mean - do
we mean the "URI"


I agree with you re the problem with pattern in this case.

The simplest pattern would be:

      pattern "[a-z][a-z0-9+.-]*:.*"; // matches the mandatory scheme

but I think you will say that either we have a complete correct
pattern, or no pattern at all ;-)
