AW: [docbook-apps] Change layout and page size for a few pages

I'm not making any progress on this, because it is still not very clear to
me.

Is it possible to call a custom simple-page-master which switches to
landscape (although the normal page orientation is portrait), if a section
element has a role attribute with the value 'landscape' (for example). Or is
there no chance of doing this?

Thanks in advance,
Bjoern
