    <p>This sample was first encoded by Gary F. Simons (Summer
           Institute of Linguistics, Dallas, TX) on January 28, 1991.
           Revised April 8, 1993 to match the specification of FSDs
           in version P2 of the TEI Guidelines. Revised again December 2004 to
           be consistent with the feature structure representation standard
           jointly developed with ISO TC37/SC4.

   </publicationStmt>
   <sourceDesc>
    <p>This sample FSD does not describe a complete feature
           system. It is based on extracts from the feature system
           for English presented in the appendix (pages 245–247) of
           Generalized Phrase Structure Grammar, by Gazdar, Klein,
           Pullum, and Sag (Harvard University Press, 1985).</p>
