Subject: [OASIS Issue Tracker] Commented: (OFFICE-2034) Table:formulaattribute and the Formula data type

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16289#action_16289 ] 

Michael Brauer commented on OFFICE-2034:

Eike, you are right, the namespace needs to be adapted.

Having thought about the issue one more time, I would like to suggest a simplification. For table:condition, style:condition and table:expression, we specify that the default is the ODFF namespace. We don't do so so far for table:formula, but I don't see a specific reason why should not specify that ODFF is the default there as well. Suggestion:

Add to 18,645 table:formula

If the namespace prefix is missing it defaults to the "urn:oasis:names:tc:opendocument:xmlns:of:1.2" namespace. 

Then, add a new conformance clause (D1.4.3) which reads: 

If the namespace prefix of a style:condition, table:condition, table:expression, table:formula or text:formula attribute is associated with the "urn:oasis:names:tc:opendocument:xmlns:openformula:1.2" namespace, or if anamespace prefix is omitted for any of these attributes, the syntax of any formula which is contained in the values of these attributes shall conform to part 2 of this specification.

>          Issue Type: Bug
>          Components: Styles, Table
>    Affects Versions: ODF 1.2
>            Reporter: Eric Patterson
>            Assignee: Michael Brauer
>             Fix For: ODF 1.2
> Section has the following to say about conforming spreadsheet documents:
> Conforming OpenDocument Spreadsheet Document  (D4.4)All table:formula attribute values shall be namespace prefixed and the namespace prefix shall correspond to the "urn:oasis:names:tc:opendocument:xmlns:openformula:1.0" namespace.
> (D4.5)All table:formula attribute values shall conform to the syntax defined by OpenFormula
> The above covers table:formula attributes and does not appear to apply to the formula data type.  This make the implementation of other structures that use the formula data type unclear.  For example, table:condition and style:condition reference the formula data type, but it is unclear whether formula strings for these should use OpenFormula syntax.  I propose that we be more clear about the intent here.  We should include something in along the lines of "Formulas MAY conform to the syntax defined by OpenFormula.  Formula strings that conform to the syntax defined by OpenFormula shall be namespace prefixed..."
> For reference, here is what the spec and schema say about this data type:
> formula
> A string containing a formula. Formulas don't have a predefined syntax, but should start with a namespace prefix that specifies the syntax used within the formula.
> - <define name="formula">
> - <!--  A formula should start with a namespace prefix,
>   -->
> - <!--  but has no restrictions
>   -->
>   <data type="string" /
