Element Usage
A Value element may appear within a Property or ScoredProperty element. The purpose of the Value element is to represent a value as a standard XML data type. The data type is specified as an XML attribute of the Value element, xsi:type. Note that not all XSD-defined or XML-defined types are supported. For a list of supported types, see Summary of Element Types. A Value element can contain only character content. Nothing else may appear as content in a Value element.
Note
Some Print Schema-defined Property and ScoredProperty elements do not contain a Value element, because their purpose is simply to be parents of subproperties. You should not add a Value element to such properties as these, properties that do not contain a Value element.
To conform to the Print Schema Framework, which requires either a Value element or subelements be present in the elements that support values, an absent or undefined value should be represented by presenting the Value element as an empty element; that is, as <Value></Value>.
Example
Define a Value of type decimal and initialize it to "128.5".
<Value xsi:type="decimal">128.5</Value>
