Post here questions and problems related to editing and publishing DITA content.
I have a reasonable pdf output from a DITA Bookmap file using custom HTML/CSS now, but would like to display the subtitle (but not the title) on the title page (since the cover image already has title and author). I imagine this requires modifying some xpath rule, but I don't really know where to start with this. How can one hide or display the Title, Alt-Title (subtitle), and Author on the front-cover page using a CSS rule? Thanks.
