| This extension point is used to define a delegate that evaluates validation expressions whose type is identified by a URI. The global EMF validation delegate registry, <samp>EValidator.ValidationDelegate.Factory.Registry.INSTANCE</samp>, is used to record the registration. |

| Following is an example of how a validation delegate can be registered: |
| <pre> |
| <extension point="org.eclipse.emf.ecore.validation_delegate" > |
| <delegate uri="http://www.eclipse.org/emf/2002/Ecore/OCL" class="org.eclipse.ocl.ecore.delegate.OCLValidationDelegate"/> |
| </extension> |
| </pre> |
| </documentation> |
| </annotation> |
| |
| <annotation> |
| <appInfo> |
| <meta.section type="apiInfo"/> |
| </appInfo> |
| <documentation> |
| The value of the class attribute must represent a class that implements <samp>org.eclipse.emf.ecore.EValidator.ValidationDelegate</samp> and has a no argument contructor. |
| <p> |
| A validation delegate can be also registered from the source code with the <samp>EValidator.ValidationDelegate.Registry.INSTANCE</samp> as follows: |
| </p> |
| <pre> |
| EValidator.ValidationDelegate.Registry.INSTANCE.put("http://www.eclipse.org/emf/2002/Ecore/OCL", new OCLValidationDelegate()); |
| </pre> |
