The change here looks like an improvement; I'll bring it to the WG's
attention.

The changes here may or may not be thought by the WG to address our
issue; I'll ask.  Reducing consistency of fragment identifiers to the
identity of secondary resources may be a brilliant solution, or may be
a brave leap from the frying pan into the fire.

I think this should be OK.

Deleting "that can be understood in a global context" is an
improvement, but the statement that "Namespaces in XML" provides a
mechanism for establishing a globally unique name remains false and
misleading.  The proliferation of this myth has needlessly cost some
Working Group months of their time, and the TAG should not be
propagating it.

Let me be very clear and explicit.  Nothing in the Namespaces Rec
defines, describes, provides, specifies, suggests, entails, depends 
on, or constitutes a mechanism for defining globally unique names.
The Namespaces Rec makes it possible to avoid one way in which
names assigned in isolation might fail to be globally unique, but
it neither requires that namespace owners ensure that local names
are unique within a namespace, nor mentions that as a necessary
or convenient step towards having globally unique names.  You may
have been misled by the rhetoric in the introduction to the first 
edition of the Namespaces Rec, but that introduction did not provide
an accurate characterization of the technical content of the 
document.

The diff is hard to read at this point, but I think it looks good.

Thank you.

I'll ask the WG.

Noted.

I believe you have identified the wrong issue; you seem to have
resolved msm1 (I am distressed to see that the references to Moby Dick
have been deleted -- otherwise, thank you), but not msm2, which
takes issues with a phrase retained in the revision.

I think this is an improvement; I'll need to re-read the spec in a
style less dominated by the red-green alternation of the places where
your diff program appears to have given up on its task and started
interleaving red and green text randomly.

Chartjunk does not wish for, merit, or reciprocate your mercy.  Kill
it!
