FWIW, Ted had proposed something on the order of allowing Documents to
have multiple named Fields, where each field has an independent token
stream. Likewise, Document sequence files could have multiple fields
per Document where each field is a string. What do you think about
something like this? The documents I work with day to day in
production are more frequently field structured than flat and in some
cases fields are tokenized while others are simply untouched. I
