I just removed the last sentence.

I'm tending in the direction of "meaning" instead of "referent"
because it is broader. I would say, for example, that rdf:type and
<about:blank> clearly "mean" but they do not obviously "refer". But I
don't feel too strongly about this.  (I would like to know what Pat
thinks...)

I know some people are bothered because they pretend not to know the
meaning of "meaning", but I think this is sort of like claiming not to
know what "is" means. I would answer: Tell me how what I've said might
be misinterpreted, how one could go wrong in applying what I've said
as a result of my using a word such as "mean". The same goes for
"refer" and "true".

I suppose if you want to refer to (or mean) 17, you can just say 17.

changed all to 'fred' ... don't know how that happened

em-ing is tantamount to quotation, and it's important that these
name/phrases not be quoted.  The report in question really *does* talk
about spoonwings, it doesn't just use the *word* "spoonwing" (in fact
it might use the neolatin Nemoptera instead; it doesn't matter for the
example).

I may flush all the variants. There are better ways to make the point.
This is just meant to be a case where Ian's architecture fails.

what a royal pain.  I'll think about it.

I have no sense of how important it is. Larry thinks it is in his tdb:
scheme draft, but it's not part of Harry's story and I don't know
whether it occurs in the wild.

mount:everest  or something... will work on it

Right.  According to the spec, the LSID "identifies" an IR if the
content-length is positive, otherwise it "identifies" something else,
as described (one hopes) in the metadata. (so you can't have an LSID
"identifying" a zero-length IR!) I doubt this is respected in the wild
though. Will elaborate.

Thanks!  Looking forward to more.

I'm still thinking about
- the title
- the overall pitch
- disposition of 3.3, which isn't like the other 3.n sections - maybe
move it to section 1

You may notice that I added a section 5.7 'no interoperability' -
David made a good point that the purpose of doing all this
coordination needs to be spelled out more clearly, so this was
supposed to say what happens if there is no agreement.

Generally I'm thinking about how to give the whole report more punch.
It's not *just* how to provide and discover URI definitions; it's how
to do so without also losing the ability to refer to IRs.
