What do you mean here? The xml output is not for the application to
verify the certificate or so. It is about displaying parts of the
certificate that cannot be extracted with the available functions.
Given that and that more and more applications have XML capability
I think some may be benefited .
 But I do not hold my breath. I expect such application developers
to comment out.

Which format is more straightforward? X.509 certificates are very very
complex to be mapped 1-1 in any simple format.

The DER format is still supported, what we are talking here is about
a convertion from der to xml.

I will check it.
