/**
* This class is used to protect access to private Credentials
* belonging to a particular {@code Subject}. The {@code Subject}
* is represented by a Set of Principals.
*
* <p> The target name of this {@code Permission} specifies
* a Credential class name, and a Set of Principals.
* The only valid value for this Permission's actions is, "read".
* The target name must abide by the following syntax:
*
* <pre>
* CredentialClass {PrincipalClass "PrincipalName"}*
* </pre>
*
* For example, the following permission grants access to the
* com.sun.PrivateCredential owned by Subjects which have
* a com.sun.Principal with the name, "duke". Note that although
* this example, as well as all the examples below, do not contain
* Codebase, SignedBy, or Principal information in the grant statement
* (for simplicity reasons), actual policy configurations should
* specify that information when appropriate.
*
* <pre>
*
* grant {
* permission javax.security.auth.PrivateCredentialPermission
* "com.sun.PrivateCredential com.sun.Principal \"duke\"",
* "read";
* };
* </pre>
*
* If CredentialClass is "*", then access is granted to
* all private Credentials belonging to the specified
* {@code Subject}.
* If "PrincipalName" is "*", then access is granted to the
* specified Credential owned by any {@code Subject} that has the
* specified {@code Principal} (the actual PrincipalName doesn't matter).
* For example, the following grants access to the
* a.b.Credential owned by any {@code Subject} that has
* an a.b.Principal.
*
* <pre>
* grant {
* permission javax.security.auth.PrivateCredentialPermission
* "a.b.Credential a.b.Principal "*"",
* "read";
* };
* </pre>
*
* If both the PrincipalClass and "PrincipalName" are "*",
* then access is granted to the specified Credential owned by
* any {@code Subject}.
*
* <p> In addition, the PrincipalClass/PrincipalName pairing may be repeated:
*
* <pre>
* grant {
* permission javax.security.auth.PrivateCredentialPermission
* "a.b.Credential a.b.Principal "duke" c.d.Principal "dukette"",
* "read";
* };
* </pre>
*
* The above grants access to the private Credential, "a.b.Credential",
* belonging to a {@code Subject} with at least two associated Principals:
* "a.b.Principal" with the name, "duke", and "c.d.Principal", with the name,
* "dukette".
