Where to find complete reference for model.rtw records

Sorry for my ignorance if this is readly available - but I'm a newbie on Simulink coder. I would like to get the complete specification for each and every record in a model.rtw. For example in Object Records for Parameters, I would like to understand what is meant by IsPublic (not only that, but many fields on that). So if anyone could help me where to find those details, it would be very helpful.
