CCXML Voxeo 1.0 Development Guide

This documentation is for CCXML 1.0-Voxeo, which has been superceded by CCXML 1.0-W3C. The CCXML-Voxeo platform is not being updated any longer. The CCXML 1.0-W3C version, however, has many new features and is actively being enhanced. If you're writing a new CCXML application, you should use CCXML 1.0-W3C. Click here for the CCXML 1.0-W3C documentation.

<createccxml> element

The <createccxml> element is used to spawn another thread of control, which begins execution with the document identified by this element. This thread of control provides independent execution and an entirely separate variable space for the CCXML documents that it executes. Such independent threads are associated with one or more event endpoints; such endpoints are the only things capable of sending events to these independent threads of execution.Note that the new thread of execution has an entirely separate address space and lifetime.

usage

<createccxml fetchid="(ECMAScript Expression)" sessionid="(ECMAScript Expression)" start="(ECMAScript Expression)">

attributes

fetchid	Data Type: (ECMAScript Expression)	Default: none - attribute is required
	This attribute indicates the ID of any document referenced in a fetch operation, which is gathered with the fetchid. A sucessful fetch completion additionally provides a property whose value is the fetch ID of the document being fetched.
sessionid	Data Type: (ECMAScript Expression)	Default: none - attribute is optional
	The sessionid attribute is an expression resolving to a platform-defined unique identifier that denotes the newly-instantiated thread of control.
start	Data Type: (ECMAScript Expression)	Default: none - attribute is optional
	Not Enabled The start attribute indicates an event object which is to be the starting event for the newly instantiated thread of control. This event will be the initial event sent to the document that has been started by this event, and the endpoint which originated this event will be inherited by the newly created thread of control.
