19.598 table:condition syntax ambiguity
---------------------------------------

                 Key: OFFICE-3491
                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-3491
             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
          Issue Type: Bug
          Components: Part 1 (Schema), Table
    Affects Versions: ODF 1.2 CD 05
            Reporter: Dennis Hamilton
             Fix For: ODF 1.2 CD 06


The special syntax for table:condition is ambiguous.

In the first paragraph, it is said that the namespace prefix (default or otherwise) applies to the syntax and semantics of values, strings, and expressions. 

To then stipulate the syntax of *value* and *string* is peculiar. 

I think the repair should be in the first paragraph, where the namespace governs only the syntax and semantics of the *expression* pattern. This allows simple table:condition forms that avoid dependence on any separate formula specification altogether. 

However it does mean that we have trouble when an *expression* under the namespace has exactly the same lexical appearance as what is defined here as a *value* or *string* pattern. I would suggest that the *value* and *string* rules would have precedence and *expression* is to be considered only when the the occurence is not a well-formed *value* or *string*. 

Finally, I note that the statement about leading "=" is worded as if it is a restriction on Part 2. I believe there is a separate proposal to strike that. 

The repair to this should allow a table:condition that has simple values and strings as operands without any use of namespace-determined expressions.
