Eric –
Lower limit -> It depends on the property. 0 (empty string without null) may be a good lower limit. For example, a string property where the value is unassigned may be set to empty string.
Upper limit -> In most cases STIX2 avoided setting an upper limit at all. For certain string enumeration properties the upper limit was set to a reasonably high value for what could be expected in that enumeration. (e.g. 256)

Subject: [csaf] [CSAF JSON Schema] limits to field lengths
The current specification does not limit the amount of data that goes into properties, such as the document title or the description fields.
The lower limit I put in the JSON schema (for just about everything), is simply a non-empty string - 1 or more characters.
Is that the right lower limit?
What's the upper limit?
Eric.
