    Simon,

    Some comments to the CIM mapping.

    1) why do you have TequilaSLS class etc. as a subclass, if there are no additional properties? This lets explode the number of classes in the model
    without adding some value. I aggree, that you need to subclasses for some of the implicit variables in order to get a defined binding?
    2) Do you refer with the BusinessDocuments to something like a contract ?
    3) I am a little confused that you model the scope as a condition, what is the rational behind?
    4) I was surprised that you model the performance guarantees as variables, why not as an object and define your one action PolicyGuarantee (perf guartee object)? IMO a variable is a data object, which is bound to the policy later, not a data object holding data values at policy definition time.

    BTW, do not use color (there is a sentence talking abbout blue objects in figure), i print it black and white.

    Marcus
