'Section 8.2.3 Extensibility' on page 57 of the BPMN 2.0 specification states:
"The BPMN metamodel is aimed to be extensible. This allows BPMN adopters to extend the specified metamodel in a way that allows them to be still BPMN-compliant."
On page 58 it is stated that:
"Every BPMN element which subclasses the BPMN BaseElement can be extended by additional attributes. This works by associating a BPMN element with an ExtensionDefinition, which was defined at the BPMN model definitions level (element Definitions)."
Is it possible to extend BPMN with an element that subclasses an existing BPMN element?
For example, is it possible to extend BPMN with a new task element that subclasses the BPMN Task, similar to how e.g. a ManualTask or UserTask subclasses the BPMN Task? If this is possible, could you provide an example?
