Thanks, Dieter. Using the repeat atribute may also necessitate relaxing the 
current restriction that an alarm event be carried out at most once per 
associated scope. Further, the alarm event should remain enabled until the 
associated scope completes or until the timer expires, whichever occurs first.

This alarm setup can be extended further similar to any standard Timer service:

<onAlarm for="duration-expr"?
	until="deadline-expr"?
	repeat="duration-expr"?
	frequency="cardinal-expr"?>*
        	    Activity
</onAlarm>

For example,

<onAlarm for = 10secs, until = today@1PM, repeat = 5 secs, frequency = 100>
     myActivity
</onAlarm>

The repeat attribute specifies the delay duration for subsequent timer 
triggers, after either the for or until time trigger completes, bounded by the 
frequency cardinal.

Peter, i would like  to request a new issue "Setting up Periodic Alarms". 
thanks for your help!
