The PACKAGE Template example is taken from ITU-T
Recommendation X.721.
This example is used to provide duration attributes
in object object classes that include this package in their specification.
This package includes two attributes, the startTime and the stopTime. It is
used in managed object classes that are used in scheduling applications.
Package Example

ATTRIBUTES
startTime GET-REPLACE,
stopTime REPLACE-WITH-DEFAULT
DEFAULT VALUE Attribute-ASN1Module.defaultStopTime
Packages may include as many or as few attributes,
notifications, actions, parameters and behaviour definitions as are
appropriate for the specification.
In many cases package template specifications contains a single clause.
These packages when used in a conditional package clause of a managed object
class are intended as optional components of that managed object class.
