Improve the Digital Identity Anchor Definition

I propose to improve this definition : Digital Identity Anchor (DIA) A verifiable credential issued by an Authoritative Register to a subject (person, company, or asset), linking a registered identifier for the subject controlled by the Authoritative Register to a cryptographic proof of authenticity and integrity. It functions like a digital certificate of ownership for the identifier. A DIA may also contain Decentralized Identifiers provided by the subject and asserted as under their control. This means that a DIA becomes a proof of identity as registered by an Authoritative Register and recognition that the subject of that identity has asserted other identifiers under their control.
