/** 
 * CSIAContentHandler Handles Session Initiation Application Content.
 *
 *	The SIA is outlined in WAP-189-PushOTA (p.16...) and provides a
 *	string listing the available connection points. Thus the body of the
 *	CPushMessage (in octets) must be parsed to retrieve this list, and
 *	then validate any connection points found. The first valid point will
 *	be used to open a connection via the Connection Manager. If no valid
 *	points exist then the handler simply quits.
