Jean-François,
This is indeed a typo - thanks for pointing it out.

  Subject: Typo in the document "Semantic Interpretation for Speech Recognition (SISR) Version 1.0" dated 1/11/2006
  It looks like this spec has a typo in it. In section 5, in the 3rd example, the <ruleref uri="#USAirport" /> should probably be enclosed in an <item> element since it is part of a <one-of>. 
   
  May you confirm that it is a typo?
   
  Thanks,
  Jean-François Peyroux
