Re: [LC] 8.3.2 The mediatype Element (PR#73)

Hi Steven,

As you know from the face to face meeting, the working group accepted a modified
form of this comment.

To simplify authoring of the mediatype child of output, a value attribute has
been added.  This helps address the mismatch you felt was problematic between
using mediatype/@ref in upload vs. in output.

However, the ref attribute was retained as an alternative because when upload
and output are being used together, they both will have a mediatype element with
a ref that indicates the same node.

The results of the change are now available in the editor's draft available from
the working group web site.

Best regards,
John Boyer
