65 * Whereas you normally write it as follows:
66 * <pre>
67 * YourParsedPattern r = (YourParsedPattern)parseable.parse(sb);
68 * </pre>
69 * write this as follows:
70 * <pre>
71 * YourParsedPattern r = (YourParsedPattern)parseable.parse(new CheckingSchemaBuilder(sb,eh));
72 * </pre>
73 *
74 * <p>
75 * The checking is done by using the <tt>rngom.binary</tt> package, so if you are using
76 * that package for parsing schemas, then there's no need to use this.
