Correct.  Another way to say it is, naming depends on policy for process
and enforcement of process.

That is, play by the rules, it works.  Else, results are error or
undefined.

Hmm, and other sources.  The local disk is where 
most action takes place.  However, should the XML system know 
the difference?  NOTE, as soon as we start talking system, we 
are talking mechanism, and resolution mechanisms are always, system.
A good aspect of the HyTime work on locators was in classifying the
types 
of resolvers by the information they need.

Quite so.  Besides, those "harmless games" are the way they organize 
indexes.   Reference designators are spatially organized "names" 
(morphologies), but if you take them away, the airplane falls out 
of the sky because they are used to locate parts/components, and 
the writers are trained to apply them.  So game or no, everyone plays.

And best matches the way humans work.  Remember them?

It is had every time someone sits down to organize or design a
hypermedia 
language.  It is fundamental. (I think I learned that from a book 
with your name on it, David.)

The reason is, James Clark says it is too hard to implement.  Given this 
discussion, does he still hold to that opinion as technical lead 
of the ERB which must draft language and vote on this?

We need to get to independent links and locator types.
The work I do in technical manuals suggests to me we 
need these badly and will implement them anyway in some 
form because they make it much simpler to express and 
maintain relationships external to the document about 
the use of a multimedia aggregate.

We have to talk about HyTime:  The Concepts.
Regardless of the IETF drafts, that is the ISO standard
for linking and locating.  I don't say we have to 
accept it as is, but at this juncture we have to 
talk about it.
