+   * Returns an {@link Escaper} instance that escapes special characters in a string so it can
+   * safely be included in XML document as an attribute value. See section <a
+   * href="http://www.w3.org/TR/2008/REC-xml-20081126/#AVNormalize">3.3.3</a> of the XML
+   * specification.
+   *
+   * <p>This escaper substitutes {@code 0xFFFD} for non-whitespace control characters and the
+   * character values {@code 0xFFFE} and {@code 0xFFFF} which are not permitted in XML. For more
+   * detail see section <a href="http://www.w3.org/TR/2008/REC-xml-20081126/#charsets">2.2</a> of
+   * the XML specification.
+   *
+   * <p>This escaper does not escape non-ASCII characters to their numeric character references
+   * (NCR). However, horizontal tab {@code '\t'}, line feed {@code '\n'} and carriage return {@code
+   * '\r'} are escaped to a corresponding NCR {@code "&#9;"}, {@code "&#10;"}, and {@code "&#13;"}
+   * respectively. Any other non-ASCII characters appearing in the input will be preserved in the
+   * output.
+   *
+   * <p>This escaper does not treat surrogate pairs specially and does not perform Unicode
+   * validation on its input.
