So I'm wondering if it would be cleaner to instead say:
In Part 1, where we define table:formula as:
NamespacePrefix':='('=')?Expression
Where Expression is defined by Part 2, OpenFormula.
(Allows 1 or 2 = signs, since the 2nd one would indicate forced recalc)
Then in Part 2, simply define Expression.
In other words, I think the equals sign is just how an OpenFormula
expression is embedded in a spreadsheet, but Part 2 doesn't really need to
say anything about it.
It is not a big deal either way, but I have a slight preference for
factoring out the spreadsheet-specific portion of the syntax into Part 1.
That way the remaining OpenFormula syntax can be more easily reused in
other contexts.
