currently in Last Call.

As with Jim, no preference as long as its in the certificate.

For DSA and DH is there any other format? For RSA there is PKCS#1 as an
alternative.

The other problem is whether there is a X9.42 DH private key format
specified anywhere at all? There is a fairly obvious extension of PKCS#3
DH PrivateKeyInfo format though.

Personally it doesn't matter, I can handle or convert any format.
