    "description": "Primitive value vocabulary shared by the other schemas: names, day names, wall-clock times, time windows, and the annotation fields. A name denotes a date set; the document either defines it under 'calendar.date_sets' or declares it under 'resolvers' and leaves it to a host binding, and the two share one namespace. A name must therefore not be spelled like a reserved word or like a literal (digits only, time-shaped, date-shaped). Times are zero-padded HH:MM; '24:00' is a token allowed only as the end of a window. A window is a half-open interval [start, end). The annotations (label, description) are inert human-facing text carried at the document and schedule levels: control characters are forbidden (description may contain LF as its only line break), and so are the invisible characters that can spoof what a reader sees (zero-width space, word joiner, BOM, and the bidi embedding/override/isolate controls; ZWJ/ZWNJ and the bidi marks stay legal for emoji sequences and the scripts that need them).",
