Get property value in JavaScript with script mediator

Question

Is there a way, inside the javascript code from WSO2 ESB's Script mediator, to get a property's value when this property has a scope different from "default" ?

In case of a property with default scope :

get-property('MyProperty') 

OR

<script language="js">
   mc.getProperty("MyProperty");
</script>

In case of a property with 'transport' scope :

get-property('transport','FILE_NAME')

OR

<script language="js">
   mc.????????
</script>

It seems that you can not get properties of other scopes than synapse using

mc.get-property("Property Name")

since mc is instance of Synapse.MessageContext in order to get other message context properties I do something like this in java, I don't know that if it is applicable in javascript or not. I do this for axis2 message context properties. Here "context" is the instance of Synapse.MessageContext.

org.apache.axis2.context.MessageContext axis2MessageContext;
            axis2MessageContext = ((Axis2MessageContext)context).getAxis2MessageContext();
