The primer example is correct, but it's not surprising you're
confused.  Un_prefixed_ attributes are _always_ unqualified, even if
there is a default namespace declaration.  So in that second example,
"country" is unqualfied, despite the 'xmlns="..."'.  This asymmetry
between elements and attributes wrt the default NS declaration is easy 
to lose track of.
