id Attribute
Identifies the Simple Messaging EXtension (smex) element.
<smex id = "uniqueName">
Remarks
The value assigned to id is a string. That string must be a valid Extensible Markup Language (XML) name that is unique within the document.
The id attribute can only be set declaratively, that is, within the declaration of a smex element. It can, however, be read programmatically.
Example
The following code demonstrates the use of the id attribute.
<smex id="mySmex" onreceive="onSmexReceive()" onerror="onSmexError()" ontimeout="onSmexTimeout()"/>
