Notes to Implementers
When overridden in a derived class, this method looks for a DefaultValueAttribute. If it finds one, it compares the value of the attribute with the property's current value. It returns

If this method cannot find a DefaultValueAttribute, it looks for a "ShouldPersistMyProperty" method that you need to implement yourself. If this is found, CanResetValue(Object) returns what "ShouldPersistMyProperty" returns. Otherwise, it looks for a "ResetMyProperty" method that you need to implement yourself. If this is found, CanResetValue(Object) returns
true. If it cannot find a DefaultValueAttribute, a "ShouldPersistMyProperty" method, or a "ResetMyProperty" method, then it returns
