Contiguous on what domain - the source or the rendering? Provided that
you mean the former, I agree. In other words, an XPointer can be
expressed as a byte range.

Wheras XSL patterns, and CSS selectors and XQL queries can return
results that are disjoint (eg, "all the foo elements which are children
of bar")

In other words, once they have been unified, how do you tell them apart.
