<synnote>
The <synnote> element contains a note (similar to a footnote)
         within a syntax definition group or fragment. The syntax note explains aspects of
         the syntax that
         cannot be expressed in the markup itself. The note will appear at the bottom of the
         syntax diagram
         instead of at the bottom of the page. This element
            is part of the DITA programming domain, a special set of DITA elements
            designed to document programming tasks, concepts, and reference information.
