Specifies the margin at the right of the printed page.
Optional string. Represents a unit of measure. The default is DL. For details about DL, see Units of measure.
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>.
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.
This value represents physical units and is unaffected by scale or drawing units. For example, if this element has a value of 0.5 in., this margin is 0.5 inch even if page units are feet. If units are not explicitly stated, this value defaults to page units.
