No, no. You don't do this inside <programminglisting>

You are trying to do presentational tagging inside this. The XML tags are for content markup. The presentation is done via XSLT Stylesheets.

In all the Docbook XML I have written/read, (Fedora, Amanda, Samba, Gentoo etc.) it's never done the way you are trying to do it.

I may be way off, but if you have an example of where you have seen it done this way, I'd love to read it.

Thanks,
Gavin.
