Author Notes
Capture notes about contributors in an <author-notes>
element.
The <author-notes> element may contain child
<fn> elements for contributor footnotes or
<corresp> elements for contributor correspondence notes.
Each <fn> or <corresp> element must have a
@id attribute which contains a unique identifier for the note which
is used for linking to the relevant contributor(s) (see Contributor Cross References).
If the <fn> or <corresp> is numbered it
must contain a <label> containing the relevant label text.
Example
<author-notes> <fn id="bk978-0-7503-4926-0ch1fn1"> <label>*</label> <p>Equal contributing authors</p> </fn> <fn id="bk978-0-7503-4926-0ch1fn2"> <label>†</label> <p>Author to whom any correspondence should be addressed.</p> </fn> </author-notes>
