<parameterentity>
Use the <parameterentity> element to identify mentions of
         parameter entities, for example, "%keyword.content;". This element enables more precise
         semantic
         searching of the DITA source; it also enables distinct formatting, such as adding
         the percentage
         sign (%) or trailing semi-colon (;) delimiters to the parameter entity name. The content
         of the
         <parameterentity> element should be the entity name without the leading
         percentage sign or trailing semi-colon. This element is part of the XML mention domain.
