Actually it could be a bit clearer on one point - do want all the
preceding / following resource elements in the whol document or within
some other scope?

If the former, "ancestor::resource | preceding::resource" and
"descendent::resource | following::resource" should do it, given the
useful comment in http://www.w3.org/TR/xpath#axes

"NOTE: The ancestor, descendant, following, preceding and self axes
partition a document (ignoring attribute and namespace nodes): they do
not overlap and together they contain all the nodes in the document."
