Also note that it is technically possible for directory servers to have multiple [{$pagename}] with different sets of schema definitions that govern different portions of the [DIT].  The schema that applies to any given entry may be determined by retrieving the {{subschemaSubentry}} [Virtual Attribute] from that entry.
