Compiled constraints are the default. The interpreter available as a fallback...

 * Arbiter of constraint implementation to use.

 * <ul>

 * <li>{@link #INTERPRETED} - the Complete OCL documents in {@code model/*.ocl}, evaluated at run time

 * by the Eclipse OCL interpreter ({@link Validator}). This is the 

 * default.</li>

 * by the Eclipse OCL interpreter ({@link Validator}). Kept as a fallback.</li>

 * <li>{@link #COMPILED} - the same invariants (embedded) converted to Java from {@code model/*.ecore}

 * ({@code tdlValidator}, {@code StructuredObjectivesValidator},

 * {@code ExtendedConfigurationsValidator}).</li>

 * {@code ExtendedConfigurationsValidator}). This is the default.</li>

 * </ul>

 * Only one of them is active, so a constraint is never reported twice. The choice is made once per

 * process with the system property {@value #PROPERTY} ({@code interpreted} or {@code compiled}): the

 * validators live in the global {@code EValidator} registry, so switching while models are being

 * validated would mix the two. In the IDE set it in {@code eclipse.ini} or the launch configuration

 * ({@code -Dtdl.validation.constraints=compiled}); for a Maven test run pass

 * {@code -DsystemProperties=-Dtdl.validation.constraints=compiled}.

 * ({@code -Dtdl.validation.constraints=interpreted}); for a Maven test run pass

 * {@code -DsystemProperties=-Dtdl.validation.constraints=interpreted}.
