Correction: James postulates that it is necessary, but *not* sufficient to retain the original character sequences.  For sequences having numeric lexical form, it is also necessary (he argues) to record in some way the fact that the value is potentially interpretable as a number, which James discusses in some of his messages.

My apologies for the original mischaracterization.
