6. Any other relevant information:

The tag "sl-dajnko" is relevant as a possible value of the @xml:lang
attribute to be used by language technology applications for
transcribing and modernising such texts, e.g. for text search in
cultural heritage digital libraries. E.g. the National and University
Library of Slovenia has plans to digitise about 4,000 pages of books
written in the Dajnko alphabet.
