headers property provides access to specialized meta
information for a specific message instance.
The headers property is an associative array with the specific
header name as the key.
The body of a message contains the instance specific data that needs to be
delivered and processed by the remote destination.
The body is an object and is the payload for a message.

The headers of a message are an associative array where the key is the header name and the value is the header value. This property provides access to the specialized meta information for the specific message instance. Core header names begin with a 'DS' prefix. Custom header names should start with a unique prefix to avoid name collisions.

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Provides access to the time stamp for the message. A time stamp is the date and time that the message was sent. The time stamp is used for tracking the message through the system, ensuring quality of service levels and providing a mechanism for message expiration.
Implementation

timeToLive:Number| Language Version: | ActionScript 3.0 |
| Product Versions: | BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The time to live value of a message indicates how long the message
should be considered valid and deliverable.
This value works in conjunction with the timestamp value.
Time to live is the number of milliseconds that this message remains
valid starting from the specified timestamp value.
For example, if the timestamp value is 04/05/05 1:30:45 PST
and the timeToLive value is 5000, then this message will
expire at 04/05/05 1:30:50 PST.
Once a message expires it will not be delivered to any other clients.
Implementation
