 Adds fields to the tender object to describe the legal basis of the contracting process – that is, the laws and regulations that govern the contracting process and that grant legal authority to the procuring entity.
 
-The `tender.legalBasis` field is a `Classification` object. Example classification schemes are [LEX](https://en.wikipedia.org/wiki/Lex_(URN)), [CELEX](https://eur-lex.europa.eu/content/help/faq/intro.html#help8) and [ELI](https://en.wikipedia.org/wiki/European_Legislation_Identifier).
+The `tender.legalBasis` object identifies the legal basis of the contracting process and, optionally, the law or regulation from which the legal basis was derived. Each law or regulation is identified by an `id` drawn from an identifier `scheme`. Example identifier schemes include [LEX](https://en.wikipedia.org/wiki/Lex_(URN)), [CELEX](https://eur-lex.europa.eu/content/help/faq/intro.html#help8) and [ELI](https://en.wikipedia.org/wiki/European_Legislation_Identifier).
 
 To identify the procedure used, whether by formal name or by legal citation, use the [`tender.procurementMethodDetails`](https://standard.open-contracting.org/latest/en/schema/reference/#release-schema.json,/definitions/Tender,procurementMethodDetails) field.
