WSDL Definition Element

WSDL Definition Element

The <definition> element must be the root element of all WSDL documents. 

It defines the name of the web service. Here is the example piece of code from last session which uses definition element.

<definitions name="HelloService" targetNamespace="uri" xmlns="uri"

xmlns:soap="uri"

xmlns:tns="uri"

xmlns:xsd="uri">

<definitions>

The definitions element is a container of all the other elements.

The definitions element specifiesthat this document is the HelloService.

The definitions element specifies a targetNamespace attribute. The targetNamespace is a convention of XML Schema that enables the WSDL document to refer to itself. It also specifies numerous namespaces that will be used throughout the remainder of the document.
