Aristotle, I was agreeing with you.

I recognize that this advisory board has a hard job. For example, in
the recent skipDays discussion -- as openly admitted by Rogers -- there
is only "thin justification" for stating GMT; but at least there is
*some* justification -- and this for an element which there is likely as
much disagreement over its meaning and support is likely at least as
sparse as ttl.

By contrast, I have seen no one bring forth any justification that the
base RSS 2.0 specification permits one to place namespaced attributes on
core elements, beyond Randy's assertion that "The schema attribute is
harmless".

And this was shortly followed up by a request that one overlook the
meaning of the word "default", which as Rogers correctly pointed out has
been in place since Netscape was actively stewarding this specification.

Based on this rather disturbing trend, I have gone from +0 to firmly -1
on this whole effort; accordingly I wish to distance myself from any and
all association with it, and I fully intent to start referring to this
as the fork of RSS 2.0 which does not respect the roadmap; and
furthermore I intend to advocate that validators like Validome provide
separate validation selections for "RSS 2.0 Harvard" and "RSS 2.0
Advisory Board", much like they currently do for "RSS 0.91 Netscape" and
"RSS 0.91 Userland".

As a point of reference, the Validome validator marks as in error any
namespaced attributes that may appear on core RSS 2.0 elements. As far
as I can tell, this was entirely based on an independent and thorough
reading of the specification; it most assuredly was not based on
anything I have said.
