Comment on XPointer and XLink: Ranges

Comment from W3C member Academia Sinica

I apologize if this has not made the last call deadline.

Ranges should be removed from XPointer and placed in XLink.

The reasons:
    1) ranges complicate XPointer implementation;
    2) ranges complicate explanations of XPointers;
    3) a pointer should point to a node or a point;
    4) a range is similar to an arc: the start and end have an affinity
to "from" and "to"

For similar reasons, I am not keen on multiple fragment specification:
it seems a shorthand for an extended XLink of some kind.
