ForceArray needs to stay

[Eike Rathke <erack@redhat.com>]

Hi,

It came to my ears ;-) there is some discussion that the ForceArray
attribute would be redundant as already implied by Array and could be
removed.

That is not the case.

ForceArray is a calculation context attribute, not a parameter type. The
ForceArray attribute is described at
http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#ForceArray

ForceArray forces all context of the argument and the expression that
results in that argument into array mode / matrix evaluation, regardless
whether the function is part of an array/matrix formula expression.

See 3.3 Non-Scalar Evaluation (aka 'Array expressions')
http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#Non-Scalar_Evaluation
2) Matrix evaluation.

I hope that helps.
