Implementation of an XML constraint parser for the UML-standard Object Constraint Language.

## Package Specification

This package provides an implementation of the {@link org.eclipse.emf.validation.xml.IXmlConstraintParser} API that supports definition of XML constraints in OCL. It consists of two classes:

- {@link org.eclipse.emf.validation.internal.ocl.OCLConstraintParser}: the constraint parser implementation that creates instances of the `OclModelConstraint` class from XML constraint descriptors
- {@link org.eclipse.emf.validation.internal.ocl.OCLModelConstraint}: the OCL-language constraint implementation

This package uses the `org.eclipse.emf.ocl` plug-in's {@link org.eclipse.emf.ocl.query.Query} class to test model elements against an OCL constraint expression. @see org.eclipse.emf.validation.xml.IXmlConstraintParser @see org.eclipse.emf.ocl.query
