MIME type related parts of Proposed Addendum to SOAP with Attachments

Here is the fulfillment of my action item regarding MIME type related
parts of the Proposed Addendum to SOAP with Attachments[1]

1.	Proposal defines a global attribute, MediaType in the
http://schemas.xmlsoap.org/2003/04/xmime namespace which specifies a
media type as defined in RFC2045 for the (conceptually) base64 encoded
content of a given element in a SOAP Envelope. If such an element does
not have this attribute "application/octet-stream" is assumed.

2.	Proposal defines a type which derives from xsd:base64Binary and
adds the above attribute.

3.	Proposal defines a global attribute Accept in the
http://schemas.xmlsoap.org/2003/04/xmime namespace which specifies a
list of media types. This attribute appears on element declarations in a
schema defining what types are accepted by a given element with
(conceptual) base64 content.
