  • Deprecated EAD 2002 elements are available in the undeprecated versions of EAD3.
  • A Schematron schema (ead3.sch) is available to validate external code lists not maintained within EAD, standard attribute value patterns, attribute or element co-occurrence not enforceable in the schema,and some encoding practices recommended for future migration.

New in EAD3 1.1.1:

  1. The foreign element is now available as a child of the ref element. (See issue #522)

New in EAD3 1.1.0:

  1. The @render attribute can now be used with the quote element. (See issue #485)
  2. The objectxmlwrap element can now be validated properly in the XSD schemas. (See issue #499) (bug fix)
  3. Manually fixed a bug that was causing the descgrp element not to validate correctly in the undeprecated DTD. (See issue #503) (bug fix)
  4. The date element is now a valid child of the part element. (See issue #505)
  5. rightsdeclaration, a new element, has been added to the control section. (See issue #506) (new element)
