<glossref>The <glossref> element is a convenience element in maps for creating a
reference to a glossary topic. It has a required @keys attribute, which forces
the author to create a key by which inline terms can reference their definition. For
example, when <glossentry> topics are used to define acronyms, this
reminds authors to create a key which <abbreviated-form> elements can
use to reference the short and expanded versions of that acronym.
