This means that parsed entities declared in the 55 * external subset need not be expanded by some classes of applications, and 56 * that the replacement text of the entity may not be available. When the <a href='http://www.w3.org/TR/2004/REC-xml-20040204#intern-replacement'> 57 * replacement text</a> is available, the corresponding <code>Entity</code> node's child list 58 * represents the structure of that replacement value.
