Resolution:
This is an issue that has been discussed in the past with no resolution.

I think this is an interesting idea for "fragment" documents (not in the
XML sense of the word).  At present you can only create a "fragment"
document along lines where NO hierarchies overlap.  Adding a cID
attribute that matches either a eID or sID would allow cleaner fragments
to be created.

I do NOT believe there should ever be a matching sID, cID, and a eID in
the same document.  (If cID is present only either sID or eID are
allowed.)
