// The ABNF in the siwe message format and RFC3986
// have a number of rules for primative strings which are
// processed many times during the parsing of a message.
// apg-js processes the terminal nodes the strings are defined by
// much more effeciently than the rule names themselves.
// The terminal nodes are processed most effeciently in the order
// TRG(%d65-90) > TBS(%d65.66.67) > TLS(%s"some string") > rule.
// Therefore, in siwe-abnf.txt these strings have been expanded
// in there terminal nodes. These tests check that the
// expansions have been done correctly.
