Considering IFERROR function

[Eike Rathke <erack@sun.com>]

Hi,

As already pointed out on the comment list, for some occasions an
IFERROR(expression;errorcase) does come handy. The function evaluates
'expression' as usual, and if that results in an error returns the
result of an 'errorcase' expression, otherwise the result of
'expression'. Also ECMA/MOOXML defines this function.

I propose to include IFERROR in our ODFF specification.
