Description

A subtitle identifies the subtitle of a document, or portion of a document.

Titles are so common, and so often the only “info” elements associated with their parent, that they (title, subtitle, and titleabbrev) are allowed outside the info element. This is a tradeoff favoring author convenience over a small amount of additional complexity in processing. However, the title elements must either all be outside of the info wrapper or all inside, you cannot have some outside and some inside.

Processing expectations

Formatted as a displayed block.
