Configuration Dependencies

Value elements that appear within ScoredProperty element may not have any configuration dependencies. Value elements that appear within Property elements may have arbitrary dependencies on the configuration.

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>
