Implementation of the `Expressions` package of the Object Constraint Lanuage version 2.0 Abstract Syntax model.

## Package Specification

This package implements the API for the structure of parsed OCL expressions, as specified by the {@link org.eclipse.ocl.expressions} package. The types in this package are not typically used by clients. Rather, instances of the abstract syntax classes are created either using the {@linkplain org.eclipse.ocl.expressions.ExpressionsFactory factory interface} or by parsing OCL text.
