BACM11 — Unclear semantics of CourseOfActionDeploysAsset

The text of the BMM 1.3 document appears to indicate that CourseOfAction can indicate that an Asset is needed by the CourseOfAction. Asset is a superclass of both FixedAsset and Resource. It would seem that this need should be modeled by the Liability that claims the needed Resource, but there is no way to specify that the CourseOfAction creates a Liability.
In addition, CourseOfAction can deploy/need a Fixed Asset or even an Offering, but the same CourseOfAction cannot discharge a Liability claim on a FixedAsset because the abstract syntax permits only discharging Liability for a Resource, not a FixedAsset
