wordwrap of methodsynopsis inside classsynopsis

Hello

I am using the default docbook tools/templates of Redhat 9.0 and am working
on a docbook 4.2 article. I have added a classsynopsis with some methods
inside, but when converted to pdf, the lines that show the methods are
clipped instead of wrapped. How could I make the classsynopsis wrap long
lines?

Regards, Jan
