Before you begin determining possible grouping arrangements for the attributes in your component, be sure that you have considered all of the manageable aspects of your component in as much detail as possible. Be sure to include all of the items that can be configured or that can be changed, as well as information that enables asset management, such as a product version number or a serial number.
The ComponentID group (ComponentID Group) is a good example of these kinds of attributes.
You can also examine existing MIF files of other components to get an idea of what kinds of attributes are defined to enable a product for management through the DMI.
