2.4. XML Schema simple types


If a message part is going to be of a simple type it is not necessary to create a type definition for it. However, the complex types used by the interfaces defined in the contract are defined using simple types.

Entering simple types

XML Schema simple types are mainly placed in the element elements used in the types section of your contract. They are also used in the base attribute of restriction elements and extension elements.
Simple types are always entered using the xsd prefix. For example, to specify that an element is of type int, you would enter xsd:int in its type attribute as shown in Example 2.2, “Defining an element with a simple type”.

Example 2.2. Defining an element with a simple type

<element name="simpleInt" type="xsd:int" />
