Relying on the stability of the semantics of XPointer makes perfectly
good sense -- if it enables you to describe your data in useful ways,
via a dependence on XPointer semantics, go for it.

As for expecting implementations of . . . well, what, exactly?  A
version of XInclude which supports full XPointer [1]?  Not likely, as
I'm not aware of any impetus towards extending the XInclude
specification in that way.

With my NLP hat on I'm a big fan of standoff markup, and we use it
extensively in our work at Edinburgh [2].  But our experience has been
that it's virtually always worth building up from a version of the
data which is tokenised at the lowest level we're ever likely to care
about, rather than trying to point into runs of text. . .

If that's ruled out because of the sheer scale of your data, or
copyright restrictions, or whatever, then you can achieve the same
effect by targetting your standoff at a virtual document, which is the
_output_ of a tokeniser on your raw data.
