# apiData

The <apiData> element specifies the actual value such as the initial value of variable, the default value of a parameter, or the value of a constant.

#### Description

This element provides a literal value such as "5 Maple Street" or "6" typically where a parameter or variable has a default or initial value.

For example, if the description of the data type is not available, you must provide the name of the related API item inside the <apiData> element and the fully qualified name of the element in the keyref attribute. The keyref attribute should provide a unique key such as a fully qualified classifier name for the named API item.

#### Example

The following example shows a simple <apiData> element for a Visual Basic property:

    <apiValue>
           <apiValueDetail>
               <apiValueDef>
                  <apiType value="month"/>
                  <apiData>25</apiData>
                  <apiDefNote>
                       Returns the day and month that the element belongs to.
                  </apiDefNote>
               </apiValueDef>
           </apiValueDetail>
       </apiValue>
