@michaelnmmeyer —
the repository tfd-nusantara-philology contains 80 texts according to https://dharmalekha.info/repositories.
according to https://dharmalekha.info/languages, under Undetermined, there are 80 files from the repository classed as linguistically undetermined.
in other words, none of the @xml:lang values in tfd-nusantara-philology, for instance <div type="edition" xml:lang="kaw-Latn"> in DHARMA_CritEdSvayambhu.xml, are picked up by the system.
can you fix this?
