[kepler-dev] custom actor MOML question

[Paul Allen]

Could somebody explain why Kepler adds a "kepler:" prefix to the port 
names in my custom actors when I instantiate the actor by class name and 
then save the kar for that component via the Kepler GUI? That change is 
confusing some downstream tools I'm using mainly because the port names 
in the <link> section of the MOML don't use the "kepler:" prefix.

Here's the MOML from the KAR for the actor.

I've attached the MOML for the model in question.
