You are right.
What does a person do with the phrase: kiss my grits.
Depends on the person.
What does a computer do with the phrase: kiss my grits.
Depends on who programmed the computer.
It always depends on the person. Ya gotta choose.
The problem is, that is not blind interoperability.
The best we can do is try to know when we can be
blind and when we need inspection to make a choice.
For that, we end up with a hierarchy or distribution
of authority who choose our choices. It is better
if decentralized and that is the URI is there to
provide. But that means a URI can't designate the
same thing every time. It can point off to an
index of things from which another process can
choose. Thus, RDDL and XML catalogs.
If we deny the semantic of the namespace, we
have said it isn't interpretable and so the
"preferred reading" has to be known a priori.
This leads to the dominant vendor.
If we say the semantic of the namespace is
interpretable, we may or may not also want
to provide a means for a local to interpret it.
This leads to dereferencing and then it is
useful to have a common mean or means to
point to the currently known choices.
This leads to RDDL and XML catalogs.
If we say we are agnostic about this issue,
(URIs are just unique strings), we leave a hole
and create a mess of unreliable expectation.
"The barnyard gate is as wide as the pasture" to quote myself.
Mutation will not often produce a survival trait. Interspeciation
and recombination can. For that to work, you need a
system to recognize close types (versions).
All you really need to know is if a URI identifies a
type or a set of closely related types. For that,
http + RDDL | catalog is ideal. Both expectation
and choice are accomodated and the author can
choose the chooser of their choices, including
themselves. It is the expression or denotation
of choice that counts.
Blind dates don't always get the job done.

The problem, I guess, goes way past "how should I label my dialect" and
encompasses "how can my various parties adapt to unavoidable changes in
And, oh, yeah - can namespace help with all of that?
