/**
 * This class provides a mechanism for specified named permissions 
 * related to the Java security framework.  These permissions have no
 * associated actions list.  They are either granted or no granted.
 * <p>
 * The list of valid permission names is:
 * <p><ul>
 * <li>getPolicy - Allows retrieval of the system security policy.
 * <li>setPolicy - Allows the security policy to be changed.
 * <li>getProperty.&lt;key&gt; - Allows retrieval of the value of the named
 * property or all properties if &lt;key&gt is a '*'.
 * <li>setProperty.&lt;key&gt; - Allows changing of the value of the named
 * property or all properties if &lt;key&gt is a '*'.
 * <li>insertProvider.&lt;key&gt; - Allows the named provider to be added,
 * or any provide if the key is '*'.
 * <li>removeProvider.&lt;key&gt; - Allows the named provider to be removed,
 * or any provide if the key is '*'.
 * <li>setSystemScope - Allows the system identity scope to be set.
 * <li>setIdentityPublicKey - Allows the public key of an Identity to be set.
 * <li>SetIdentityInfo - Allows the description of an Identity to be set.
 * <li>addIdentityCertificate - Allows a certificate to be set for the public
 * key of an identity.
 * <li>removeIdentityCertificate - Allows a certificate to be removed from the 
 * public key of an identity.
 * <li>clearProviderProperties.&lt;key%gt; - Allows the properties of the
 * named provider to be cleared, or all providers if key is '*'.
 * <li>putProviderProperty.&lt;key%gt; - Allows the properties of the
 * named provider to be changed, or all providers if key is '*'.
 * <li>removeProviderProperty.&lt;key%gt; - Allows the properties of the
 * named provider to be deleted, or all providers if key is '*'.
 * <li>getSignerPrivateKey - Allows the retrieval of the private key for
 * a signer.
 * <li>setSignerKeyPair - Allows the public and private key of a Signer to
 * be changed.
 * </ul>
 * <p>
 * There is some degree of security risk in granting any of these permissions.
 * Some of them can completely compromise system security.  Please exercise
 * extreme caution in granting these permissions.
