Nice work on the web interface to the validator. Before you dive back into
the spec, could you troubleshoot these 500 errors I'm getting on your

URL: http://das.biopackages.net/das/genome

With the "guess" radio button I get:

   500 Internal error
   TypeError: GuessFromHeader() takes exactly 2 arguments (1 given)

With any other radio button I get:

   500 Internal error
   AttributeError: BodyError instance has no attribute 'args'

>   - check that the content-type agrees with the document type
>   - check that it's well-formed XML; report error where not
>   - check that the root element matches the document type
>   - check that it passed the Relax-NG validation;
>   - report the id and href fields which are empty strings
>   - report if any date fields are not iso dates
