DSS signatures

As we develope support for PEM, we are also considering support for DSS
as an alternate for RSA signatures.  Has anyone considered werhe the p,
q, and g values go?  Ie.  are they a part of the key in the signature
the way the RSA "e" is a part of the key, or do they get added to the
signature on the message?

Any Help or suggestions would be appreciated.
