/* token values
 *
 *  tokens are produced by a schema-specific tokenizer function
 *  this function is purposely abstract because it may rely upon
 *  whatever information it needs to perform its task. the only
 *  requirement is that it produce these tokens as its output.
 *
 *  an empty name input must produce no tokens. in this case,
 *  there is no name to tokenize or data to produce.
 *
 *  a non-empty name must produce 1 or more tokens of output.
 *  all tokens must be ordered by starting character position.
 *
 *  if a name does not conform to any pattern recognized by the
 *  tokenizer, then the tokenizer emits a single token of "unrecognized"
 *
 *  if a name conforms to some pattern but does not have any
 *  substitution tokens, the tokenizer emits a single token of "recognized"
 *
 *  if a name may be tokenized, then the resulting tokens should
 *  describe only the portions of the string that should be removed
 *  from the name, e.g. "X" or "Y".
 *
 *  the standard coordinates "X".."L" are given in unsigned decimal.
 *  alternate representations are contained within their respective
 *  namespaces: "signed", "hex" and "octal".
 *
 *  the special coordinate "Q" represents the 454-specific encoding
 *  of X and Y into base-36, where the formula for Q is:
 *    Q = 4096 * X + Y
 *  and ASCII encoding:
 *    0..25 => "A-Z", 26..35 => "0-9"
