Anchoring entity-specific disclosures: new guidance lands
XII has published draft guidance exploring how taxonomy relationships can be leveraged to anchor entity-specific disclosures (ESDs), an important part of open reporting frameworks. The document, produced by the Entity Specific Disclosure Task Force, aims to help regulators and taxonomy designers ensure that extension elements remain meaningful, structured and comparable.
While the “wider-narrower” link remains the primary anchoring tool under the European Single Electronic Format (ESEF), this guidance dives deeper. It categorises relationships into three tiers: traditional structures like calculation and presentation trees; relationships currently in use with anchoring potential (like cubes and extensible enumerations); and a new generation of semantic relationships that promise enhanced clarity and machine-readability.
Improving anchoring practices is central to achieving consistent, comparable and decision-useful digital disclosures, especially as taxonomy design matures.
