Disclosure Management supports three types of instance validation:
Presentation—Validates the instance document for conformance to XBRL specifications. For example, if a mapped concept is of Duration period type and instance document contains one date in the corresponding Context, the presentation validation should fail, because Duration period type requires Start and End dates to be defined.
Calculation—Validates all computed values in the instance document per the calculation relationships defined within the taxonomy. It uses the calculation relationship defined in calculation schema while taking care of the Weight attribute for numeric facts.
Formula—Validates all computed values in the instance document per the formulas defined within the taxonomy. Formulas in taxonomy facilitate business analysis and forecasting as they support calculations of data type “boolean” (true or false) and “string” in addition to “monetary” item types.
