ConstReadonlyDate: "date"ReadonlyDateTime: "dateTime"ReadonlyDisplay: "display"The text a cell SHOWS: under a filter the displayed text, so $1 is a cell holding 1 under
$0; under a format or a validation, where nothing is shown at evaluation, the value's own
text. Type text. Excel's filter equal and its values list compare this way;
equalTo under no selector is value equality.
ReadonlyLogical: "logical"ReadonlyNumber: "number"ReadonlyText: "text"ReadonlyTextLength: "textLength"ReadonlyTime: "time"ReadonlyWhole: "wholeNumber"A selector is how a condition reads a value: it gates (a value of another kind is not this
kind) and projects (date is the day, textLength the count). No selector is "any value".
Membership is not among them. A list is the BuiltInOperatorNames.InSet operator, which
every selector offers; the name 'list' is still read, as no selector with inSet.
