Method ConditionRefresh
Allows a Client to request a Refresh of all Condition instances that currently are in an interesting state (they have the Retain flag set).

This includes previous states of a Condition instance for which the Server maintains Branches. A Client would typically invoke this method when it initially connects to a Server and following any situations, such as communication disruptions, in which it would require resynchronization with the Server. This method is only available on the ConditionType or its subtypes. To invoke this method, the call shall pass the well known MethodId of the method on the ConditionType and the ObjectId shall be the well known ObjectId of the ConditionType object
