/**

|
* Classes and functions for the template engine.
|
|
*
|
|
* Templates are either:
|
|
* + Creating or Editing, (a Container or DN passed to the object)
|
|
* + A predefined template, or a default template (template ID passed to the object)
|
|
*
|
|
* The template object will know which attributes are mandatory (MUST
|
|
* attributes) and which attributes are optional (MAY attributes). It will also
|
|
* contain a list of optional attributes. These are attributes that the schema
|
|
* will allow data for (they are MAY attributes), but the template has not
|
|
* included a definition for them.
|
|
*
|
|
* The template object will be invalidated if it does contain the necessary
|
|
* items (objectClass, MUST attributes, etc) to make a successful LDAP update.
