 Please keep in mind that if there are multiple solutions to a particular action designator, i.e. it resolves to different plans, the first one that is defined will be executed. Ordering is not yet implemented and should probably be taken care of explicitly in the plans anyway. Please keep in mind that if there are multiple solutions to a particular action designator, i.e. it resolves to different plans, the first one that is defined will be executed.

- +Summary: **make sure an action designator you use for plans can only be resolved to one unique CRAM plan.**
-Also, if the same action designator can be executed by both a process module or a high-level plan, the precedence will always be given to the process module as it should get the most specific designators. +

-Summary: **make sure an action designator you use for plans can only be resolved to one unique CRAM plan and that the process modules always get as input one level more detailed action designator than the plan. Even better is to not have similar action designators for PMs and those for plans.**+
