  /**
   * Attribute represents an XML-style attribute of an
   * Element. Typically, the allowable values are controlled by its
   * declaration in the Document Type Definition (DTD) governing this
   * kind of document.
   * <P>
   * If the attribute has not been explicitly assigned a value, but has
   * been declared in the DTD, it will exist and have that default. Only
   * if neither the document nor the DTD specifies a value will the
   * Attribute really be considered absent and have no value; in that
   * case, querying the attribute will return null.
   * <P>
   * Attributes may have multiple children that contain their data. (XML
   * allows attributes to contain entity references, and tokenized
   * attribute types such as NMTOKENS may have a child for each token.)
   * For convenience, the Attribute object's getValue() method returns
   * the string version of the attribute's value.
   * <P>
   * Attributes are not children of the Elements they belong to, in the
   * usual sense, and have no valid Parent reference. However, the spec
   * says they _do_ belong to a specific Element, and an INUSE exception
   * is to be thrown if the user attempts to explicitly share them
   * between elements.
   * <P>
   * Note that Elements do not permit attributes to appear to be shared
   * (see the INUSE exception), so this object's mutability is
   * officially not an issue.
   * <P>
   * DeferredAttrImpl inherits from AttrImpl which does not support
   * Namespaces. DeferredAttrNSImpl, which inherits from AttrNSImpl, does.
