/**
 * A container for validation metadata.
 *
 * The container contains constraints that may belong to different validation
 * groups. Constraints for a specific group can be fetched by calling
 * {@link findConstraints}.
 *
 * Implement this interface to add validation metadata to your own metadata
 * layer. Each metadata may have named properties. Each property can be
 * represented by one or more {@link PropertyMetadataInterface} instances that
 * are returned by {@link getPropertyMetadata}. Since
 * <tt>PropertyMetadataInterface</tt> inherits from <tt>MetadataInterface</tt>,
 * each property may be divided into further properties.
 *
 * The {@link accept} method of each metadata implements the Visitor pattern.
 * The method should forward the call to the visitor's
 * {@link ValidationVisitorInterface::visit} method and additionally call
 * <tt>accept()</tt> on all structurally related metadata instances.
 *
 * For example, to store constraints for PHP classes and their properties,
 * create a class <tt>ClassMetadata</tt> (implementing <tt>MetadataInterface</tt>)
 * and a class <tt>PropertyMetadata</tt> (implementing <tt>PropertyMetadataInterface</tt>).
 * <tt>ClassMetadata::getPropertyMetadata($property)</tt> returns all
 * <tt>PropertyMetadata</tt> instances for a property of that class. Its
 * <tt>accept()</tt>-method simply forwards to <tt>ValidationVisitorInterface::visit()</tt>
 * and calls <tt>accept()</tt> on all contained <tt>PropertyMetadata</tt>
 * instances, which themselves call <tt>ValidationVisitorInterface::visit()</tt>
 * again.
