The type of error: The parser can't parse a formula that Excel accepts.
The input: W1.
The XLParser takes W1 as a CellToken (priority 100) and, it doesn't even try NameToken (priority -800). It then fails to parse the dot. For these situations, there is the NamedRangeCombinationToken... that fails because of a likely regex.
