Attributes

Unit

Optional string. Represents a unit of measure. Default values are described in the preceding table. For details about a particular unit of measure, see Units of measure.

F

Optional string. Represents the element's formula. This attribute can contain one of the following strings: "someFormula" if the formula exists locally, "No Formula" if the formula is locally deleted or blocked, or "Inh" if the formula is inherited.

If the attribute is not present, the element's formula is a simple constant, for example, <element>5</element>.

Err

Optional string. Indicates that the formula evaluates to an error. The value of Err is the current value (an error message string); the value of the element is the last valid value.

V

Optional string. Represents the null string condition for a string cell value. In some cases it is helpful to distinguish between an empty string cell null and a null string cell value. This attribute is used to distinguish between these forms of an empty value.

The C element is relevant only when contained in a DocumentSheet , PageSheet , or Shape element. It is ignored when contained in a StyleSheet element.

The SolutionXML element should be present only in a C element contained in a Scratch element. If it is contained within other elements it is ignored and a warning is written to the warning log file.
