An internal cross-reference. This is an empty element, displayed as a link to the element identified with its @linkend (its target element), with contents generated from the target (its @xreflabel or, on certain elements where @xreflabel is not available, an autogenerated label).
This element is the preferred method for inserting any kind of cross-reference including cross-references to bibliographic citations (<bibliomixed> elements).
Elements for which cross-referencing text can be generated without a @xreflabel include <appendix>, <equation>, <figure>, <footnote>, <note>, <section>, <table>, or any type of list (<itemizedlist>, <orderedlist>, <variablelist>) that has a <title>.
