[kepler-dev] Plans for Actor kars?

[Matt Jones]

Kevin,

Chad is away for the week.  Here's my memory of the decisions:

We decided to stick with the KAR format because of the desire to include 
data in the package as well as the MoML.  Later it may be extended as we 
discussed for the binary components.

It is the identifier for the actor executable class.  I too think it 
should be the same for all actors that share a class like the web 
service actor.  IIRC, right now it isn't because Chad's parser requires 
it to be unique, which I think Chad was planning on fixing.  Chad will 
have to clarify on this one.
