Comment 3 for bug 239854

From the design I try to have formattings with functional properties, instead of layout properties. What I mean by that is that a head1 may look different when exporting to e.g. html but still has the role of being a heading.

In this case it is not clear to me if you want to add a new formatting type which is rendered big, bold and underlined, or if you use underline in a different way. Implementing this is not as easy as it sounds because the current code always assumes that styles do not overlap, so I would like to have a good understanding of the problem at hand before starting to hack away.
