The abstract text should not contain HelpTag markup because the abstract may be read and displayed by applications that don't recognize markup.

The <abstract> element is automatically assigned the ID string _abstract. An author-defined ID cannot be assigned. The _abstract ID can be used with the <link> element, but not with the <xref> element.

Abstract text may contain an optional <head>.
