Dale,

So, then it seems you are advocating we add an additional "gr" tag.
However, wouldn't the absence of "mp" or "rc" for a GRUU indicate that
the GRUU wasn't mapped.  I guess it is not harmful to add a unique tag
for cases where a GRUU is used, but do you have a use case where this
is relevant?

Thanks,
Mary.
