I'm thinking that "an expression" should be "a query".

It might be better to say "initial dynamic context", since the initial static
context would have been created before the static analysis phase.

(Also, it's somewhat incorrect to refer to *the* initial context, since there
could be more than one [e.g., one per module]. The description of the static
analysis phase has the same problem. But fixing it will probably wait until

There's no such thing as "dynamic expressions". You might mean "initializing

I think that sentence would fit better as the last or second-last sentence of
para 3 in

Also, I think we're missing a sentence such as:
    If the Module Feature is supported, the dynamic context is extended with
    variable values and function implementations from imported modules.
(i.e., the dynamic evaluation phase is not just concerned with the main module,
it also involves processing the prologs of library modules). But maybe that
should wait for 1.1 as well.
