Each pattern type must be followed by a pattern modifier that indicates how to handle cases where one or more defined patterns is found to be a sub-pattern of a larger input pattern. In this case, the Master Index Standardization Engine must know how to prioritize each defined pattern that is a part of the larger pattern. There are two pattern modifiers.
* - An asterisk indicates that the priority weight for the matching pattern is averaged down equally with the other matching sub-patterns.
+ - A plus sign indicates that the priority weight for the matching pattern is not averaged down equally with the other matching sub-patterns.
