Release 4.10.1 is a patch release to remove a Schematron constraint introduced in the 4.10.0 release. This constraint flagged as an error the case of two or more sibling declarable elements appearing in the TEI header without the required attributes. Because TEI projects use these elements in the TEI Header in contexts that do not involve att.declarable, we are removing the Schematron rule introduced in 4.10.0. For now the language guiding the constraint is still present in the prose, as it has been since P2. (#2750 and PR # 2751).

Note: patch releases do not have codenames.
