I cannot imagine how you suppose this from anything I have said. I have argued
long and consistently that content always requires the operation of a process to
elaborate semantics, which are required for any interpretation. If what I
secretly believe is as you assert, it is so secret that I have never been aware
of thinking it, let alone arguing it.

Deny what? That the operation of a process accurately implementing Caesar's
calendrical calculations yields the result which Caesar's definitions require?

At the point at which you learn this fact, you have instantiation. They are one
and the same outcome. The specific annotation which you proposed needs the
operation of a different process (as you concede below) to elaborate (at least
potentially) different semantics. And in this case the semantic outcome is
different:  one process yields the 15th, the other yields the 13th. You can
appeal to a third process, like time travel, to elaborate different semantics in
light of which the two outcomes are the same. That does not change what each
process yields through its own operation, nor how those outcomes are different.

It could, and in the example you gave, it does.

I'm not. I'm simply pointing out the conflict. And I would, I think, be the last
person to argue that the text had any viewpoint, or intent, or any such
significant semantics until it was operated upon by some process which elaborated
some specific semantic outcome.

There are semantics elaborated by the operation of a process appropriate for
manipulating syntax expressing a date in AUC form. There is no one date
semantics, just as there is no one date syntax. Semantics are elaborated on each
occasion by the operation of process against syntax. Different syntax or
different process and you yield (at least potentially) different semantic
outcome. And there is not, in the world of concrete markup, an abstract date
syntax, only instances of particular syntactic usages.

No. The XML 1.0 Recommendation gives us the basis for determining whether a given
text is well-formed. That is why I am in the practice of XML. We can say that a
well-formed text is an instance of XML syntax. Beyond that we can apply various
processes to various artifacts of that syntax in order to elaborate particular
semantics.

Beef with them all you want. I, on the other hand, say that there is text, there
are processes, and there are the particular semantics elaborated by the operation
of specific processes against specific text on specific occasions. How could my
argument be any more different from this strawman?
