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
