How many kind moddle descriptors attribute

[tcguoxing]

I want to create my own moddle descriptors based on bpmn.json. I have found some attributes confusing me. Is there document can explain these attributes, for examle:
isAbstract, isBody, isReference and type …, what are they mean?

Best Regards
