9.6.2 The reference language
The reference language variant is the variant in which the original content is written. The reference language variant is a property of a document, in other words it can be different for each document (but not for branches within the same document). The reference language variant of a document can be changed at any time.
In Daisy, we use the convention that if the reference language variant for a document is set, the document is considered to be under translation management.
In the Daisy Wiki, the reference language can be set by opening the document in the editor, you will find the reference language below the "Misc" tab.
