PropertyDefinition :: internalTypeId - Internal type number

The property holds the internal type number, which has been assigned by the system. The internal type number is an identifying number for system data types and application defined data types:

• elementary data types: -32 < type ID < 0
• Enumerations: type ID = -100
• ODABA resource types: 0 < type ID < 400
• GUI resource types: 400 < type ID < 1000
• Application types: 1000 < type ID

Usually, this is the internal type ID from the associated type definition. Since elementary data types not always refer to a type definition, the type ID may be read directly from the property definition.
