We are using the "xrefstyle" feature introduced with Asciidoctor 1.5.6.1 (see http://asciidoctor.org/docs/user-manual/#customizing-the-cross-reference-text )
We use the "short" for the "xrefstyle" attribute because it corresponds to what we wanted since we are using asciidoctor (I guess we had this with our LaTeX setup).
