Historically, the numbers on the terminal productions have used the same order and numbering as originally used in SPARQL. These seem to have drifted over time. For example, PNAME_NS in SPARQL is [140] and in Turtle is [139s]. ECHAR is [160] in SPARQL, [159s] in Turtle, and [153s] in N-Triples.
Once the dust has settled on other grammar changes, we might want to strive for some consistency across the different grammars.
