+ *
+ * Please refer to the libpkix Programmer's Guide for detailed information
+ * about how to use the libpkix library. Certain key warnings and notices from
+ * that document are repeated here for emphasis.
+ *
+ * All identifiers in this file (and all public identifiers defined in
+ * libpkix) begin with "PKIX_". Private identifiers only intended for use
+ * within the library begin with "pkix_".
+ *
+ * A function returns NULL upon success, and a PKIX_Error pointer upon failure.
+ *
+ * Unless otherwise noted, for all accessor (gettor) functions that return a
+ * PKIX_PL_Object pointer, callers should assume that this pointer refers to a
+ * shared object. Therefore, the caller should treat this shared object as
+ * read-only and should not modify this shared object. When done using the
+ * shared object, the caller should release the reference to the object by
+ * using the PKIX_PL_Object_DecRef function.
+ *
+ * While a function is executing, if its arguments (or anything referred to by
+ * its arguments) are modified, free'd, or destroyed, the function's behavior
+ * is undefined.

+/* PKIX_RevocationChecker
+ *
+ * PKIX_RevocationChecker provides a standard way of revocation checking.
+ * Caller should configure two set of tests(represented at lists of
+ * RevocationMethod objects) to be performed on the leaf and on the rest of
+ * the chain certificates.
+ *
+ * PKIX_RevocationMethods provide a standard way for the caller to insert
+ * their own custom revocation checks to verify the revocation status of
+ * certificates. This may be useful in many scenarios, including when the
+ * caller wishes to use their own revocation checking mechanism instead of (or
+ * in addition to) the default revocation checking mechanism provided by
+ * libpkix, which uses CRLs and OCSP. 
+ *
+ * Once the caller has created the RevocationMethod object(s), the caller
+ * then specifies the RevocationMethod object(s) in a RevocationCheck object
+ * and sets it into a ProcessingParams.

+ * FUNCTION: PKIX_RevocationChecker_Check
+ * DESCRIPTION:
+ *
+ * Verifies revocation status of the certificate. Issuer cert is given to

+ * PKIX_RevocationChecker_CreateAndAddMethod function) and a point of chain
+ * building process at which PKIX_RevocationChecker_Check was invoked.
+ * For security reasons, the cert status is checked only against cached

+ * verification stage after trust anchor was identified.
