Elements related to the glossary specialization are not
defined as part of the glossary topic type, but are often used in
conjunction with those elements.
abbreviated-form
The <abbreviated-form> element represents a reference to a term that might appear in an abbreviated form (often an acronym). The long and short forms of the term are generally defined in a <glossentry> topic. Processors display the referenced term when rendering an <abbreviated-form> element.
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.
glossgroup
The <glossgroup> is a specialized topic that can contain multiple <glossentry> topics within a single document.
