From 1c906fb186517f6ea85b3cb1f0a9fb54c1c2c314 Mon Sep 17 00:00:00 2001 From: Carsten Milling Date: Sun, 12 Jul 2026 17:21:03 +0200 Subject: [PATCH] Add Schematron check for antilabe @part sequence Verify that elements form a valid antilabe sequence: part="I" must be followed by part="M" or part="F"; part="M" must be preceded by part="I" or part="M" and followed by part="M" or part="F"; part="F" must be preceded by part="I" or part="M". Adapted from the schematron by @daliboris in https://github.com/daliboris/plays-encoding-framework, reimplemented with plain XPath 2.0 to match DraCor's existing constraint style.
