tag
empty element tag
end tag
start tag

   <language, text> An {SGML}, {HTML}, or {XML} {token}
   representing the beginning (start tag: "<p ...>") or end (end
   tag: "</p>") of an {element}.  In normal SGML {syntax} (and
   always in {XML}), a tag starts with a "<" and ends with an
   ">".

   In {HTML} jargon, the term "tag" is often used for an
   "{element}".
