xpath/xslt/xquery effectively treat these names as being in the
namespace with name "" without any obvious problems.
name equality works exactly the same for names in the namespace "" as it
does for other namespaces, so your <p> and my <p> are considered equal by
xpath if we both have a p in no-namespace.

I'm not sure what is "obvious" here? I could use exactly the same
example with the elements being in a namespace:

<a xmlns="data:,x" >pi</a>

<a xmlns="data:,x" >
  <b>3.14156</b>
</a>

In what way is this situation any different from the no-namespace case?
