1 Introduction

The XPointer xmlns() scheme is intended to be used with the XPointer Framework [xptr-framework] to allow correct interpretation of namespace prefixes in pointers, for instance, namespace-qualified scheme names and namespace-qualified element or attribute names appearing within scheme data.

The key words must, must not, required, shall, shall not, should, should not, recommended, may, and optional in this specification are to be interpreted as described in [rfc2119].

The terms pointer part, scheme, XPointer processor, and namespace binding context are used in this specification as [defined] in the XPointer Framework specification.

The formal grammar for the xmlns() scheme is given using simple Extended Backus-Naur Form (EBNF) notation, as described in the XML Recommendation [XML].
