  Like for a non-default namespace i.e. with a given prefix:
    - in XPath a non qualified name refers to a not-namespaced name
    - to address a name in the default namespace, one must bind that
      namespace URI to a prefix and use that prefix in the XPath expression
 
 XPointer inherits this aspect from XPath since it only expands XPath 
addressability, not the syntactic or base steps aspects.

  yes, XPointers are subpart of URIs which have to be context independant,
that's why xmlns() scheme was added (i.e. make sure namespaces bindings in
XPointer expressions are not inherited from the context).
