A: Completeness requirements
    1. XPointers must identify XML information objects, rather than
       necessarily their expressions in the raw XML syntax of a given
       For example, an XPointer can identify an element but not a tag,
       and (potentially) an attribute; but not the equal-sign or
       quotations that expressed it.


B: Robustness requirements

    1. The same structure must be generated regardless of whether the
       parser was WF or validating.
