=head1 NAME

XML::Grove::XPointer - deprecated module once intended for XPointer

=head1 SYNOPSIS

THIS MODULE IS USED BY XML::Grove::Path, it does not implement any
 current version of XPointer

=head1 DESCRIPTION

This module implements a very tiny portion of an old draft of
XPointer.  XML::Grove::Path still uses this module, but both modules
will be obsolete when a real XPath and XPointer module become
available.
