DOCBOOK-APPS: Suppressing Certain Warning in Jade|Openjade

Hello!

How can I suppress certain warnings based on the type of the warning. More
specifically, I'm referring to suppressing the DTDDECL warnings. I know
that there is no way to get rid of them, but I guess there is a way to
suppress them using the "-w" switch. How can I get a list of all the
warnings that can be disabled.

Thanks for any advice!

Greetings,
