GEMS12 — No PingMessage/Response defined in XML schema

The XML PSM sections and attached schema do not define a ping response message
Proposed Resolution: Potential XML Ping & PingResponse messages

<?xml version="1.0" encoding="UTF-8"?><PingMessage gems_version="1.1" target="testDevice1" timestamp="1234.98765"

token="ABCD" transaction_id="1" xmlns="http://www.omg.org/gems" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.omg.org/gems GEMS_base_types.xsd" />
<?xml version="1.0" encoding="UTF-8"?><PingResponse gems_version="1.1" target="testDevice1"

timestamp="1234.98765" token="ABCD" transaction_id="1" xmlns="http://www.omg.org/gems" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.omg.org/gems GEMS_base_types.xsd"> <Result>SUCCESS</Result> <description>I'm Here!</description></PingResponse>

Add a section to the PIM describing the Ping message and response. Correct the XSD and add a section to the XML PSM describing the message format.
