Update of /sources/public/2002/ws/desc/wsdl20 In directory hutz:/tmp/cvs-serv24964/wsdl20 Modified Files: wsdl20-primer.html Log Message: Editorial correction: use the term "extension" instead of "extensibility" for elements and attributes.

(For more on QNames see [<cite><a href="#XMLNS">XML Namespaces</a></cite>] section 3 <a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/#ns-qualnames">Qualified Names/a>.)</p></dd></dl><p></p><p> Now we can start describing the GreatH service. </p></div></div> ! ! <div class="div3"> ! <h4><a name="basics-types"></a>2.1.3 Defining Message Types</h4><p>We know that the GreatH service will be sending and receiving messages, so a good starting point in describing the service is to define the message types that the service will use. We'll use XML Schema to do so, because WSDL 2.0 processors are likely to support XML Schema at a minimum. However, WSDL 2.0 does not prohibit the use of some other schema definition language.</p><p>WSDL 2.0 allows message types to be defined directly within the WSDL 2.0 document, inside the <code>types</code> element, which is a child of the <code>description</code> element. (Later we'll see how we can provide the type definitions in a separate document, using XML Schema's <code>import</code> mechanism.) The following schema defines <code>checkAvailability</code>, <code>checkAvailabilityResponse</code> and <code>invalidDataError</code> message types that we'll need. </p><p>In WSDL 2.0, all normal and fault message types must be defined as single <em>elemnts</em> at the topmost level (though of course each element may have any amount of substructure inside it). Thus, a message type must not directly consist of a sequence of elements or other complex type. </p><div class="exampleOuter"> ! <p class="exampleHead" style="text-align: left"><a name="example-initial-types"></a><i><span>Example 2-3. </span>GreatH Message Types</i></p> [...3991 lines suppressed...] !
