match-path
Specifies a subtree in the directory that is used in matching the entry.
When the <match-path> element is specified in a <placement-rule> element, the prefix attribute is compared to the src-dn attribute of the <add> element. The entry matches if the entry is in the subtree specified by the prefix. The name space of the prefix is the source of the add operation.
The format of the prefix is dependent upon the name space.
