Ambiguity in ODFF 'forced recalculation' definition

[Mike Kaganski <mikekaganski@hotmail.com>]

Hi!

In ODF v3 part 4 section 3.5 "When recalculation occurs" [1], there is a 
mention of "forced recalculation marker" that is said to "indicate that 
(formulas) should always be recalculated during a recalculation process" 
(note the "always").

Later, in section 5.2 "Basic Expressions", the "forced recalculation" 
marker is defined as an extra EQUALS SIGN after the first one that 
starts formula; and is documented to indicate that the formula "should 
be recalculated whenever one of its predecessors it depends on changes".

Note how the second definition of the effect ("whenever one of its 
predecessors it depends on changes") differs from the first one 
("always"). In addition, the second definition seems largely unneeded, 
because it would only make difference between the cases where a formula 
is in a cell that is *not* displayed, and is not a dependency of any 
displayed formula, and the implementation does not generally recalculate 
such formulas; while the first definition is more general, and allows to 
convert any formula into volatile formula.

I believe that a decision should be made, which definition is the 
correct one, and the two occurrences should be synchronized (or probably 
the redundancy in definition should be removed, by using something like 
"In addition, a forced recalculation marker may be used to modify when 
recalculation occurs, as described in the syntax below").
