/** 

 * CSIContentHandler handles Service Indication content  

 *

 * This handler takes ownership of the SI message and processes it

 * according to the Reception rules 

 * [WAP Service Indication version 08-Nov-1999 section 7.2]

 * and either stores the message or deletes it.

 *

 * OVERVIEW:

 *	The main body of this class and its functionality lies within

 *	HandleMessage (asynchonous). This :

 *		1. takes ownership of the push message

 *		2. validates the message and generates a parsed document tree

 *		3. extracts the message attribute values from document tree 

 *		4. processes the received message

 *		5. finishes

 *

 *	Step 4: is an algorithmic implementation of 7.2 Reception rules

 *		from WAP Service Indication 08-Nov-1999 with the exception

 *		that the final step (step 5: handling of information specified

 *		in the info element) has not been implemented as this is a UI

 *		feature. 

 *

 *		NB: a received message with no creation date will be stored (unless

 *		its action is set to delete or the expiry condition is met). This 

 *		means that the si-id in the message store will not be unique.
