XML object classes are defined in PackageNameTypes.xsd files. PackageName is the name of the package. All object class definitions begin with a header containing:

• Name

• Type - class

• Abstract - yes/no

• Singleton - yes/not

• Category - one of service, topology, general

• Deployable - yes/no

• Read access - list of users or all

• Write access - list of users or all

• Inheritance Hierarchy - inheritance tree

The following figure is an example of an Object Class Type definition header for the AdditionalTextAttribute class in the fm package.
