The element <send> defines parameters to send to the called application. The element <send> contains an optional element <sendName> and the element <variableRef>, the element <globalPropertyRef> or the element <stringValue>. Send parameters can be either local variable or global property values or strings. The element <sendName> defines the parameter name used by the external application. When used in conjunction with the element <variableRef>, the element <globalPropertyRef> or the element <stringValue>, it clearly defines each sending parameter.
