<compound-kwd-part> Compound Keyword Part

Individual component of a multi-part keyword (for example, a code, the code’s meaning).

Usage/Remarks

Some keywords are a simple word or phrase; such keywords should generally be tagged using the <kwd> element. The <compound-kwd> element is used when keywords are composed of multiple parts, such as:
  • a code and its meaning, or
  • an abbreviation and its expansion.
It is recommended that the @content-type attribute be used to indicate the role of each <compound-kwd-part>. Example values corresponding to the examples given in the list above, might be code, term for the meaning, abbrev, and expansion.
Related Elements
One <compound-kwd-part> element is used to mark each component of a complex keyword that is contained within a <compound-kwd>.
