The process of TEI content models proceeds apace and (as might be expected) is turning up a few oddities in some unfrequented corners. For example, the content model of <langUsage> is currently (in the source) <content> <oneOrMore xmlns="http://relaxng.org/ns/structure/1.0"> <choice> <!-- <rng:ref name="p"/>--> <ref name="language"/> </choice> </oneOrMore> </content> Now, this is clearly nonsense : you can't have an alternation with just one option. But did we really want to remove the possibility for having a purely documentary <langUsage> such as <p>Contains various unrecognised Polynesian languages</p>? Can anyone remember why we made this change ? I would have expected to see something like <choice> <oneOrMore> <rng:ref name="model.pLike"/> </oneOrMore> <oneOrMore> <rng:ref name="language"/> </oneOrMore> myself.
