| <p><b>Variables</b></p> | |
| <p> | |
| Variables are used in BPEL to store | |
| inbound and outbound messages for examination and manipulation by the | |
| business logic; they can also be used to save intermediate results and | |
| the process state. There are three kinds of variable declarations: | |
| messages types, XML Schema types and XML Schema elements. | |
| </p> | |
| <p> | |
| The <strong>Details</strong> tab allows | |
| you to define the variable declared type and its structure by | |
| selecting from known types. Once a variable type has been defined, the | |
| structure of the variable is shown. Clicking on the hyperlink will | |
| open the WSDL or XML Schema editor for the selected type or element. | |
