Values of this type denote a (sorted) set of zettel identifier.

A set is different to a list, as no duplicate values are allowed.

Allowed values

Must be at least one sequence of 14 digits (“0”–“9”), separated by space characters.

Query comparison

A value matches an identifier set value, if the value matches any of the identifier set values.

For example, “000010060325” is a prefix “00001006032000 00001006032500”.

Sorting

Sorting is done by comparing the String values.
