+  <modulesummary>The CosEventChannelAdmin defines a set if event service interfaces that  enables decoupled asynchronous communication between objects and implements generic (untyped) version of the OMG COSS standard event service.</modulesummary>
+  <description>
+    <p>The event service defines two roles for objects: the supplier role and 
+      the consumer role. Suppliers supply event data to the event channel and 
+      consumers receive event data from the channel. Suppliers do not need to 
+      know the identity of the consumers, and vice versa. Consumers and 
+      suppliers are connected to the event channel via proxies, which are managed
+      by ConsumerAdmin and SupplierAdmin objects.</p>
+    <p>There are four general models of communication.  These are:    </p>
+    <list type="bulleted">
+      <item>The canonical push model. It allows the suppliers of events to initiate the
+       transfer of event data to consumers. Event channels play the role of 
+      <c><![CDATA[Notifier]]></c>. Active suppliers use event channel to push data to 
+       passive consumers registered with the event channel.</item>
+      <item>The canonical pull model. It allows consumers to request events from 
+       suppliers. Event channels play the role of <c><![CDATA[Procure]]></c> since they 
+       procure events on behalf of consumers. Active consumers can explicitly 
+       pull data from passive suppliers via the event channels.</item>
+      <item>The hybrid push/pull model. It allows consumers request events queued at
+       a channel by suppliers. Event channels play the role of <c><![CDATA[Queue]]></c>.
+       Active consumers explicitly pull data deposited by active suppliers via 
+       the event channels.</item>
+      <item>The hybrid pull/push model. It allows the channel to pull events from 
+       suppliers and push them to consumers. Event channels play the role of 
+      <c><![CDATA[Intelligent agent]]></c>. Active event channels can pull data from 
+       passive suppliers to push it to passive consumers.</item>
+    </list>

+      include necessary <c><![CDATA[hrl]]></c> files by using:<br></br><c><![CDATA[-include_lib("cosEvent/include/*.hrl").]]></c></p>
+    <p>There are seven different interfaces supported in the service:</p>
+    <list type="bulleted">
+      <item>ProxyPushConsumer</item>
+      <item>ProxyPullSupplier</item>
+      <item>ProxyPullConsumer</item>
