- * <p>This is not part of core-only SAX2 distributions.</p>
- *
- * <p>The <em>specified</em> flag for each attribute will always
- * be true, unless it has been set to false in the copy constructor
- * or using {@link #setSpecified}.
- * Similarly, the <em>declared</em> flag for each attribute will
- * always be false, except for defaulted attributes (<em>specified</em>
- * is false), non-CDATA attributes, or when it is set to true using
- * {@link #setDeclared}.
- * If you change an attribute's type by hand, you may need to modify
- * its <em>declared</em> flag to match.
