| /** |
| * Immutable in-memory representation of grammar. |
| * |
| * <p> |
| * This object represents a set of constraints that can be checked/ |
| * enforced against an XML document. |
| * |
| * <p> |
| * A {@link Schema} object is thread safe and applications are |
| * encouraged to share it across many parsers in many threads. |
| * |
| * <p> |
| * A {@link Schema} object is immutable in the sense that it shouldn't |
| * change the set of constraints once it is created. In other words, |
| * if an application validates the same document twice against the same |
| * {@link Schema}, it must always produce the same result. |
| * |
| * <p> |
| * A {@link Schema} object is usually created from {@link SchemaFactory}. |
| * |
| * <p> |
| * Two kinds of validators can be created from a {@link Schema} object. |
| * One is {@link Validator}, which provides highly-level validation |
| * operations that cover typical use cases. The other is |
| * {@link ValidatorHandler}, which works on top of SAX for better |
| * modularity. |
| * |
| * <p> |
| * This specification does not refine |
| * the {@link java.lang.Object#equals(java.lang.Object)} method. |
| * In other words, if you parse the same schema twice, you may |
| * still get <code>!schemaA.equals(schemaB)</code>. |
