`size` must be set whenever `offset` is set, so any offset-based read always
carries an
-explicit `size`. A self-reference (`uri` not set) must set `offset`, and
therefore also
-`size`. `size` may be omitted only for a whole-file external reference, where
the range
-runs to the end of the referenced file.

current file
+cannot be referenced: `offset` and `size` apply only to data referenced by
`uri`.
Review Comment:
What if `uri` is the current file?
