Sudarshan S Chawathe scripsit:

Fixed.

Adopted.

I suppose it should not be.  Text added.

Yes, there is (except for the association procedures, which have been flushed).

Well, it's an example, so I've left it with the examples.  The comment
before it has been rewritten to refer to lseqs, though.

Most languages are dramatically underdescribed, and at least one is
dramatically overdescribed.  Still other languages are simultaneously
overdescribed and underdescribed.  Welsh pertains to the third category.
