match-path
Specifies a subtree in the directory that is used in matching the entry.
When the <match-path> element is specified in a <matching-rule> element, the prefix attribute is used to specify the starting point of the <query> element that is generated from the matching rule. The name space of the prefix is the destination of the add operation.
The format of the prefix is dependent upon the name space.
