To use it you need to provide a XML file with "hyphenation_patterns_path" prop.
Supposedly packages are the go to tool to provide the file with OpenSearch service. However package upload is rejected with "Copy failed" error, detailing in "Validation failure: package contains unsupported content."
... since obviously the XML file is not a plain word list.
But how else can the XML file be provided to OpenSearch? Or is it just not possible at all?
