+# Template customizations
+
+This directory contains Pandoc template files
+derived from Quarto version 1.6.40.
+
+## Tagged PDF/A
+
+The PDF workflow is tweaked to embed semantically structured metadata,
+a.k.a. [tagged PDF] files,
+which conforms to the [PDF/A-2b] standard,
+using experimental LaTeX hint
+[`\DocumentMetadata` declaration][DocumentMetadata].
+
+PDF/A comes in multiple flavors.
+[Some guidelines] advice to use the 2b flavor,
+so that is what is currently done.
