Edited Unassigned: DataValidation : Operator property is wrong ( always "any"). [14896]

When I read Excel which includes data-validation , the Operator property is always set "any".

There are many options when setting data-validation ( between , greaterThan , and so on ... ) , but setting doesn't be reflected to Operator property in ExcelDataValidation.

I think the problem is probably related to XML. Because XML "@operator" attribute is already set incorrect ( always "any").
