// If we do not throw the exception, resolve the flavor from the inheritance

// Diableoverride is defined in the CIM Spec to mean that the value cannot change

// The other characteristics including the flavor can change apparently. Thus, we

// need only confirm that the value is the same (2.2 pp 33). Strange since we

// would think that override implies that you cannot override any of the

// characteristics (value, type, flavor, etc.) This also leaves the question

// of NULL or no values. The implication is that we must move the value

// from the superclass or declaration.

// ATTN: there seems to be a problem with the CIM schema that marks the

// abstract qualifier as non-overridable but then they override it.

// For now it is just disabled. This problem exists in both XML and

// CIM schema.
