 * Zod schema for validating submission requirement values.

 * - purpose: An optional string.
 * - from: An optional string.
 * - from_nested: An optional array of submission requirement objects.
 * - count: An optional number.
 * - min: An optional number.
 * - max: An optional number.

 * @example
 * // Valid usage
 * submissionRequirementSchema.parse({
 *  rule: 'all',
 *  name: 'name',
 *  purpose: 'purpose',
 *  from: 'from',
 * }); // Returns { rule: 'all', name: 'name', purpose: 'purpose', from: 'from'}
 *
 * // Invalid usage (will throw ZodError)
 * submissionRequirementSchema.parse({}); // Throws error: Object has missing required properties
