Certainly.  The question I was addressing is this: Is it good design
to use the same name for elements that have truly different semantics,
which is a sort of pun?  I'd say no, even if context disambiguates:

<myStuff>
  <rock>
    <hardness>7</hardness>
    <!-- on the Mohr scale: as hard as quartz -->
  </rock>
  <booze>
    <hardness>50</hardness>
    <!-- alcohol content: could be U.S. proof, U.K. proof, or percentage,
         you have to look in the documentation -->
  </booze>
</myStuff>

This design rule is orthogonal to the use of namespaces.

If a soldier is asked why he kills people who have done him no harm, or a
terrorist why he kills innocent people with his bombs, they can always
reply that war has been declared, and there are no innocent people in an
enemy country in wartime.  The answer is psychotic, but it is the answer
that humanity has given to every act of aggression in history.  --Northrop Frye
