Dennis Hamilton commented on OFFICE-3435:
-----------------------------------------

@Rob,

If we accept the intermediate case, I don't think a note is useful.  Basically, the OpenFormula evaluator needs to communicate the URL parameter value via a HOST-DEFINED BEHAVIOR.  We could pile that onto the HOST-RESOLVER behavior, even though that is a stretch, but we need the disposition of the URL to be determined by HOST-DEFINED behavior wherever the HYPERLINK function is implemented.

I would say something like "the value determined for the URL is communicated to the HOST-DEFINED context for use as a URL associated with the result of the evaluation."  The evaluation continues whether or not any use is made of the URL.  The fact that the value delivered by HYPERLINK for use in the evaluator need not be the final value of the formula being calculated should be irrelevant, too.

In ODF 1.2 Part 1, we would then say exactly what that means, whether we take the last-given one (makes sense), and how it impacts the cell, in the case of a <table:table-cell> table:formula calculation.

[I'm amazed how much separation-of-concerns and non-leaking of abstractions is showing up in my interactions today.]

> ODF 1.2 CD05 Part 2 has an inexplicable definition for the HYPERLINK function.
> The description asserts that there is an effect on a cell.
> The description assrts that there is an effect on a cell even if the function's occurrence is not needed in the evaluation of the formula.
> The description asserts that there is a coordinated effect in how an IRI is composed (or multiples delivered) from individual occurrences of the HYPERLINK function in the same expression.
> The description asserts unjustifiable requirements on the implementation of an evaluator.
> Finally, the examples of this function are used to refine the definition.  Only the simplest examples can be inferred from the definition.
> It appears that incidental consequences of a specific implementation are being appealed to, without concern for what is essential and good enough for an OpenFormula case and no matter what odd behaviors that implementations might have for cases that defy well-definedness.
