You can use an XML Schema or RELAX NG simple type with a base type of
xs:token and enumeration facets.

(To ease the transition to a schema, if it's an issue, you can use Jame's
Clark's trang, http://www.thaiopensource.com/relaxng/trang.html, which does
a bang-up job converting DTDs to several flavors of schema.)
