RE: Changes to 3.1.5.1 Evaluating Static and Dynamic Function Calls

I agree with these comments, and committed a new version that attempts to address them.

Where 5.a says:
     then the new function's implementation is associated
     with a static context and a dynamic context in one of
     two ways, depending on the function implementation
It doesn't actually depend on the function's implementation, but rather on
whether we've already associated contexts with that implementation.

Within 5.b.i.A's
     <phrase diff="add" at="bug29277">
       The static context for this evaluation
       ...
     </phrase>
there are two embedded diff-phrases, which doesn't make much sense.
The inner markup should be eliminated.

5.b.ii says:
     An API used to invoke external functions must state whether the static
     and dynamic contexts are available to a function that is invoked.
The "whether" is odd, because we've just said that they *are* made available.

And:
     The F&O specification states how the static and dynamic contexts are
     available to a function that is invoked
No, it doesn't really say "how the contexts are available", rather it
specifies how each function *depends on* (or uses) the info in those
contexts (if at all).

And the XPath-only sentence:
     A host language must state whether and how the static and dynamic
     contexts are available to a function that is invoked.
As above, the "whether" is odd. Maybe "available to" should be "used by".
But really, the host language spec would only have that responsibility for
functions that *it* adds to the mix. E.g., the XSLT spec doesn't have to
state how F+O functions use context info.

---

BTW, I noticed that the new Note ("XQuery 3.1 is a host language...") isn't
getting diff-highlighted, even though it has diff="add" in the source.
