Parameter Descriptor Element

A parameter element defines a template parameter. Template parameters must be declared with this element to be used in template instantiation.

This element may only appear as a child of a server-template element or a service-template element.

The following attributes are supported:

Attribute	Description	Required
`name`	The name of the parameter. For example, if `index` is used as the name of a parameter, it can be referenced using `${index}` in the server or service template.	Yes
`default`	An optional default value for the parameter. This value is used if the parameter is not defined when a server or service is instantiated.	No

Here is an example to demonstrate the use of this element:

XML

<server-template id="MyServerTemplate"> 
    <parameter name="index"/> 
    <parameter name="exepath" default="/opt/myapp/bin/server"/> 
    ...
</server-template>
