A sort key value within the queried partition: an entity name the partition
contains, or that name followed by a delimiter and an id.
Named because it is now the operand type of four conditions rather than the
body of one. A range over the sort key is a range over these strings, which
is what makes { $gte: "Order#100", $lt: ... } mean anything — the ordering
is lexicographic over the stored key.
