<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.
See appendix for information about this element in OASIS document type shells.
