That's exactly what I meant.

I looked at it more from a programmers perspective (and I think a lot of
people that will eventually use JSON-LD do). If consider the context as kind
of a header file where all variable declarations are made, I think it would
make sense. So you basically say: In the context (that's the "header") I set
up and declare everything that I'll then use in the main JSON-LD document,
i.e., I map terms and prefixes to IRIs and set their data type. I think
programmers won't have any problems in understanding that the context isn't
about instance data. Even more so if they use external context documents. On
the other hand, the term coercion is typically used to refer to implicit
(automatic) type conversions in programming.
