My point is that the concepts of "specific files" and "generic editor"
seem like they define objects or ways that objects act or are acted on
but in fact they define *intentions*.

Then Word is intended to load specific files. It always uses the same
structure, they just have different names and modified contents. :-)

"True moddability" is again a definition of *intent*.

Varying from case to case where the same actions are performed or the
same objects are involved reduces the certainty and thereby the value
and the likely adoption of the CC licenses.

OK, sure. I'm not trying to drag this off topic. :-)

I am *entirely* sympathetic to the aim, but I think that is overreach
compared to the power afforded to other artists.
