[OASIS Issue Tracker] Commented: (OFFICE-3029) 19.598:Table:Condition - location of namespace prefix seems scoped incorrectly

Dennis Hamilton commented on OFFICE-3029:
-----------------------------------------

It turns out that CELL("CONTENT") doesn't do the job.  I think we need an OpenFormula "CURRENT_CONTENT()" function that can be used in filter expressions (and also other interesting formulas, since it does not imply recursion if the formula not producing a new value or it doesn't force recursion.  (There should be no recursion if the evaluation does not change the current content.)

I continue to recommend that is-true-formula be allowed in the syntax for the condition.

I also note two things about when evaluation of filters must occur:

1. The existing cell-content() references that are allowed tend to imply that something has already been accepted or exists as the cell content.

2. The condition can be for a warning or an informational message, not a rejection of the supplied value.

3. This suggests that an appropriate interpretation is as if the value already exists in the cell and that a persistent document may contain table cell values that do not satisfy the filter conditions for one reason or another.

That seems like the most clear-cut way to handle this.

> In section 19.598, it has the following text: "The value of this attribute should be a namespace prefix, followed by a ":" (COLON, U+003A), followed by Boolean expression. ".  This implies placing the namespace prefix at the beginning of the condition string, immediately preceding the condition.  For example:
> table:condition="of:cell-content-is-decimal-number() and cell-content-is-between(1,[.B1])"
> Given that the OF namespace specifies the syntax for an expression used as a value in a condition, is this the best place for it?  Should it be as follows instead?
> table:condition="cell-content-is-decimal-number() and cell-content-is-between(1,of:[.B1])"
