RE: [office-formula] Expression Calculation: expression = formula?

[robert_weir@us.ibm.com]

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.
