 * Wraps a {@link SchemaBuilder} and does all the semantic checks

 *
 * <h2>Usage</h2>
 * <p>
 * Whereas you normally write it as follows:
 * <pre>
 * YourParsedPattern r = (YourParsedPattern)parseable.parse(sb);
 * </pre>
 * write this as follows:
 * <pre>
 * YourParsedPattern r = (YourParsedPattern)parseable.parse(new CheckingSchemaBuilder(sb,eh));
 * </pre>
 *
 * <p>
 * The checking is done by using the <tt>rngom.binary</tt> package, so if you are using
 * that package for parsing schemas, then there's no need to use this.
