I'm surprised there are not cross references in the two hypertexts - the
BNF and the BNF(Children)
[examines internal state more closely]
Let me rephrase that...
It would be sensible to construct the two hypertexts with
cross-references to each other, and increase the usefulness of each to
those using them.
I ought to be surprised, I think, because by now we have known this sort
of stuff for a long time.
