Part 2 6.13 Add CURRENTVALUE function
-------------------------------------

                 Key: OFFICE-3494
                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-3494
             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
          Issue Type: Sub-task
          Components: Needs Discussion, OpenFormula, Part 2 (Formulas)
    Affects Versions: ODF 1.2 CD 05
            Reporter: Dennis Hamilton
             Fix For: ODF 1.2 CD 06


The CURRENTVALUE( ) function is an additional Information Function that provides access to the existing value in the context for which the OpenFormula formula is being evaluated.

This function corresponds to the current-content( ) function defined in ODF 1.2 style:condition and table:condition attributes and it has the same purpose:

Whenever the evaluation is in a context where there is a current value, that value is made available to the evaluation as the result of CURRENTVALUE( )..

Whenever the evaluation is in a context where there is a current cell on behalf of which the formula is being evaluated, the current value of that cell is the value of CURRENTVALUE( ).  

CURRENTVALUE( ) is a special form of reference that delivers a value based on the context of evaluation.

When there is no current value available, CURRENTVALUE( ) returns an error-type value.   If the current value is an error-type value, that error is returned.

Evaluation of CURRENTVALUE( ) shall not induce recalculation.  It does not constitute a recursive reference of any kind.
