Hello there.

I am having a bit of difficulty discerning in P.S. 3.4/2004 C.
what the range-matching actual forma is.
That is,
" - " means "<03.02.05>[space]-[space]<04.02.05>" or

This is not difficult to deal with, the correct way will show up easily
during testing but what I am asking whether there is a BNF (of some
kind) defintion of such rules that I can't find.

Thank you,
