This patch re-implements path references (&label which expands to the referenced node's full path) in terms of the bytestring expression infrastructure. Internally this is implemented as a constant bytestring expression containing nothing but the marker to insert the path reference later. Logically it would be neater to have the expression itself expand directly to the right value itself, but for now we're evaluating these expressions before all the tree's paths have been constructed.
