<p>
The <code>ExtendedLength</code> interface serves as a tagging interface to
 indicate that the applet supports extended length APDU. If this interface is
 implemented by the applet instance, the applet may receive and send up to 32767
 bytes of APDU data.
 </p><p> The APDU command header in the APDU buffer will use the
 variable length header defined in ISO7816-4 with a 3 byte Lc value when the Lc field in
 the incoming APDU header is 3 bytes long. The incoming data in that case will begin at
 APDU buffer offset 7.
