    Description ( 
       "The CIM_ActionSequence association defines a series of "
       "operations that either transition a SoftwareElement, "
       "referenced by the CIM_SoftwareElementActions association, to "
       "the next state or removes the element from its current state. "
       "The Action classes participating in this association must have "
       "the same value for the Action.Direction property - since they "
       "are either part of a sequence to transition a SoftwareElement "
       "into its next state or to uninstall it. The next-state and "
       "uninstall Actions associated with a particular SoftwareElement "
       "must be a continuous sequence. \n"
       "ActionSequence is an association that loops on the Action "
       "classes with roles for the \'prior\' and \'next\' Actions in "
       "the sequence. The need for a continuous sequence imples: "
       "(1)Within the set of next-state or uninstall Actions, there is "
       "one and only one Action that does not have an instance of "
       "ActionSequence referencing it in the \'next\' role. This is "
       "the first Action in the sequence. (2) Within the set of "
       "next-state or uninstall Actions, there is one and only one "
       "Action that does not have an instance of ActionSequence "
       "referencing it in the \'prior\' role. This is the last Action "
       "in the sequence. (3) All other Actions within the set of "
       "next-state and uninstall Actions must participate in two "
       "instances of ActionSequence, one in a \'prior\' role and the "
       "other in the \'next\' role." )]
