/**
* This abstract class defines an SPI that Metro Application developers can implement, to handle custom
* validation of Nonces used in conjunction with Password-Digest Authentication. A repeated nonce would
* generally indicate a possible replay-attack.
*
* The SPI implementation class needs to be
* specified as a META-INF/services entry with name "com.sun.xml.xwss.NonceManager".
* A default implementation of this SPI is returned if no entry is configured.
