What is the precise reason that many of the constraints in UML 1.5, for 
Constraint, Stereotype, TagDefinition, ModelElement (section 2.6.3, 
pages 2-80 ff.) give the following problem?

-- cannot be specified with OCL, level M2 not accessible 

In other words, why is level M2 (the metametamodel) not accessible with 
OCL?
