Yes - that's why I have choosen wishlist severity.

Hmmm, lintian seems to be able to compute the values - at least it
usually comes up with a valid value in the warning text.  Since lintian
is in Perl as well the code should be somehow available to some extend.
Unfortunately Perl is not my mother tongue and I guess you will have a
less harder time to parse this.
