/** 

 * 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.
