Intended category of I-Ds

I believe the I-D guidelines should be revised to recommend
authors include a statement indicating which RFC category the
I-D is intended to be published in.  This allows the reviewer
to apply determine a level of scrutity based upon the intended
category.

I've come a cross a number of WG I-Ds which did not indicate
their intended category AND the WG I-D didn't provide appropriate
clarification.  (Yes, I've brought this to the attention of
the WG chairs and I-D authors).

Comments?
