OCL Conformance
OCL Conformance rules are applied to validate an element, relationship or attribute against any defined constraints in the Object Constraint Language (OCL). OCL is used to describe expressions on UML models, and to express constraints free of side-effects. You can add OCL constraints to any element, relationship or attribute in Enterprise Architect.
Define OCL Constraints
You can add an OCL constraint to a model object by setting OCL as the Constraint type in the object 'Properties' dialog.
