missing namespace identifier in example 1 of SOAP primer

hi.
Noticed what I think may be a teeny omission, but then again maybe I'm wrong.

Here is the beginning of example 1 in the SOAP primer:

<?xml version='1.0' ?>
<env:Envelope xmlns:env="http://www.w3.org/2001/12/soap-envelope">
<env:Header>
<m:reservation xmlns:m="http://travelcompany.example.org/reservation" 
env:actor="http://www.w3.org/2001/12/soap-envelope/actor/next" 
env:mustUnderstand="true"> 
<m:reference>uuid:093a2da1-q345-739r-ba5d-pqff98fe8j7d</reference>

shouldn't that last closing tag be </m:reference>?
