Remarks
IAttributeRule is for setting rules based on attributes for object classes. They describe the legal values for a field in an object class. For example, you might set an attribute rule that specifies wood poles can only be within a certain height range. You do this by establishing a range domain for pole heights and then using an attribute rule to apply this domain to a particular field in the pole object class, probably the height field.
