      <p>Release 4.10.1 is a patch release to remove a Schematron
      constraint introduced in the <ref
      target="https://www.tei-c.org/Vault/P5/4.10.0/doc/tei-p5-doc/readme-4.10.0.html">4.10.0</ref>
      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 <name
      type="class">att.declarable</name>, we are removing the
      Schematron rule introduced in 4.10.0. For now the language
      guiding the constraint is still present in <ref
      target="https://www.tei-c.org/Vault/P5/4.10.1/doc/tei-p5-doc/en/html/CC.html#CCAS2">the
      prose</ref>, as it has been since P2. (<ref
      target="https://github.com/TEIC/TEI/issues/2750">#2750</ref> and
      <ref target="https://github.com/TEIC/TEI/pull/2751">PR #2751</ref>).</p>
      <p>Note: patch releases do not have codenames.</p>
