Define character length limits for parameters in IDS specifications to enforce data validation requirements and ensure compliance with buildingSMART standards.
Instructions
Add string length restriction.
Args: spec_id: Specification identifier or name facet_index: Index of facet in location (0-based) parameter_name: Which parameter to restrict (e.g., "value") base_type: XSD base type (e.g., "xs:string") ctx: FastMCP Context (auto-injected) location: "applicability" or "requirements" (default: "requirements") length: Exact length min_length: Minimum length max_length: Maximum length
Returns: {"status": "added", "restriction_type": "length", "spec_id": "S1"}
Example: Add length restriction to attribute value: Tag must be between 5 and 50 characters
