I've spent a few hours putting together a bare bones DITA -> PDF template using Chemistry, and I'm impressed with how intuitive things have been so far. However I'm stuck on a specific thing.
We're putting some metadata on the cover. Let's say, for example, "AA123456 revision 1".
The difficult bit (for me!) is that it has to be presented vertically (top to bottom, left-to-right).
Is there a way of doing that ?
Any help is welcome

(I haven't yet tried to lift the metadata from the map's topicmeta yet, but that will be the next step).
Thanks!
