Hi Wouter,

Many thanks for raising these issues.
I'll comment each one below...

You're right. I've just fixed the specification and I plan to release a
new version during the next weeks.

I agree with you, and I think it should not be a problem for the existing
applications if we make these changes:

- Make dc:language an optional element.
- Change the cardinality of dc:language to "unbounded".
- Change the recommendation about the content of dc:language by including 
ethnologue codes as another option (probably the main option). Note that
it will still be just a recommendation, not a normative statement.

I'll wait to see if there's some feedback about this before making the

This one I think it's OK to keep it as it is. A TAPIR accesspoint is just
an URL, so it's really up to the provider to decide which pattern to use.

Thanks again,
