<cd:parameter name="title">

<cd:paramdoc>is the title that will be used to create the section heading. Alternative versions of the title may also be specified, as explained below. The main title is used if these are not specified.

If you need a line break in a title, you can use <tt>\\</tt>, it will create a line break on location, but a space in list and marking context. Unfortunately it will appear literally in PDF bookmarks.</cd:paramdoc>
