+ * <dsig:DSAKeyValue> processing
+ *
+ *
+ * The DSAKeyValue Element (http://www.w3.org/TR/xmldsig-core/#sec-DSAKeyValue)
+ *
+ * DSA keys and the DSA signature algorithm are specified in [DSS].
+ * DSA public key values can have the following fields:
+ *
+ * * P - a prime modulus meeting the [DSS] requirements
+ * * Q - an integer in the range 2**159 < Q < 2**160 which is a prime
+ * divisor of P-1
+ * * G - an integer with certain properties with respect to P and Q
+ * * Y - G**X mod P (where X is part of the private key and not made
+ * public)
+ * * J - (P - 1) / Q
+ * * seed - a DSA prime generation seed
+ * * pgenCounter - a DSA prime generation counter
+ *
+ * Parameter J is available for inclusion solely for efficiency as it is
+ * calculatable from P and Q. Parameters seed and pgenCounter are used in the
+ * DSA prime number generation algorithm specified in [DSS]. As such, they are
+ * optional but must either both be present or both be absent. This prime
+ * generation algorithm is designed to provide assurance that a weak prime is
+ * not being used and it yields a P and Q value. Parameters P, Q, and G can be
+ * public and common to a group of users. They might be known from application
+ * context. As such, they are optional but P and Q must either both appear or
+ * both be absent. If all of P, Q, seed, and pgenCounter are present,
+ * implementations are not required to check if they are consistent and are
+ * free to use either P and Q or seed and pgenCounter. All parameters are
+ * encoded as base64 [MIME] values.
+ *
+ * Arbitrary-length integers (e.g. "bignums" such as RSA moduli) are
+ * represented in XML as octet strings as defined by the ds:CryptoBinary type.
+ *
