Question
BOOKTITLE MAINTITLE
What's all this about – all the ditamaps I've made so far (outside FM) simply have a <title>, so I'm curious as to what these elements are for/do, and frustratedly curious about how to set/select/define them. The on-line help … doesn't, really:
<booktitle>
The <booktitle> element contains the title information for a book, including the library title, main title, subtitle, and other titles (as required).
