The Object and Variable node classes define a number of attributes which are not defined on the TypeDefinition. This means there is no way to capture the default values for these attributes in the Type Model.

For example, all instances of a Boiler produce events but that information is not captured in the BoilerType. When a Boiler is instantiated its EventNotifer is set to a default of None. A server could have some behind the scenes logic to ensure the EventNotifier is set properly but I was thinking it would make more sense to simply add a DefaultEventNotifier attribute to the BoilerType

This issue can be addressed by adding the following optional attributes:

DefaultAccessLevel
DefaultUserAccessLevel
DefaultMinimumSamplingInterval
DefaultHistorized
DefaultEventNotifier
