driver-state
Allows the DriverShim to save any required state information that it needs when it is initialized again.
<!ELEMENT driver-state ANY >
The ANY element allows you to add tags for whatever state information your driver needs to determine whether a transaction completed successfully. The DirXML engine keeps a queue of pending transactions and does not delete a transaction until the DirXML driver sends back the state of the transaction.
A state element can be included in any output or input command which the driver sends to the DirXML engine.The DirXML engine stores the information in the DirXML-DriverStorage attribute of the DirXML-Driver object and returns the information in the init-params command when the driver shim, subscriber shim, and publisher shim are started.
The VR Test driver saves the state information for the DriverShim. This information consists of a timestamp and a count. This sample XML starts with the <input> element.
...
<input>
<init-params>
...
<driver-state>
<time-stamp>2000-02-18 10:06:52.610</time-stamp>
<run-count>51</run-count>
</driver-state>
</init-params>
</input>

If you have binary data to save as state information, you will need to encode it as base64.
