<expan> Expansion

<expan> is a generic element which encodes the expanded form of a word, including acronyms. The ABBR attribute may be used to supply the abbreviated form of the word or words for indexing or searching, but it is not required. See also <abbr>.

<expan> may be used within <abstract>, <archref>, <bibref>, <container>, <creation>, <descrules>, <dimensions>, <emph>, <entry>, <event>, <extent>, <extref>, <extrefloc>, <item>, <label>, <langmaterial>, <langusage>, <materialspec>, <origination>, <p>, <physdesc>, <physfacet>, <physloc>, <ref>, <refloc>, <repository>, <subtitle>, <titleproper>, <unitdate>, <unitid>, and <unittitle>;.


  • ALTRENDER – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
  • AUDIENCE – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
  • ID – not required. Creates an ID for element. Can be used for linking.
  • ABBR – not required. May contain the abbreviation of the word.


<expan> may only contain PCDATA.


<p>[...] During those years, she served as a <expan abbr="PCV">Peace Corps Volunteer</expan> in the Philippines.</p>

(Note: The above expaneviation would be best used in a repository which dealt with Peace Corps documents enough to make “PCV” a common abbreviation.)
