Anish, Yes, it does add just a little more clarity to what the spec is going to lay out for the reader. Thanks. -- Tom Jordahl Macromedia Server Development -----Original Message----- From: Anish Karmarkar [mailto:Anish.Karmarkar@oracle.com] Sent: Wednesday, September 29, 2004 1:45 AM To: Tom Jordahl Cc: www-ws-desc@w3.org Subject: Media Types doc: addition to the intro section Tom, During the Toronto F2F you had expressed a concern about the introduction section of the media types doc -- that it does not tie everything together. During the discussion of this, it was agreed to add additional text to the intro section which explains how the problem is solved. We took an action to propose wordings for the additional text. Here is my attempt to address the concern. Current text: --8<-- Data sent and received over the Web typically uses the MIME media type defined by [IETF RFC 2046], as the type system. For example, "image/jpeg", "application/pdf". There is a need to indicate the media type of the XML element content, for example, in messages sent and received by Web services. There is also a need to express the media type information using [XML Schema: Datatypes], which is the type system used by [WSDL 2.0 Part 1]. This would allow XML-based applications, such as Web services, to utilize the widely deployed and supported MIME media type infrastructure. [XOP] and [MTOM] enables one to serialize binary content (element content that is in a canonical lexical representation of the xs:base64Binary type) in an optimized way using MIME packaging. There is a desire to specify the media type information of such binary element content in a standard way in the [XML Information Set] and not just in the optimized serialization of that Infoset. This document specifies: * a mechanism to indicate the media type of an XML element content whose type is xs:base64Binary or xs:hexBinary. * a mechanism to indicate in XML Schema the expected media type(s) for an element content whose type is xs:base64Binary or xs:hexBinary. -->8-- Proposal: Change the last para to - --8<-- This document specifies: * an attribute (xmlmime:contentType) to indicate the media type of an XML element content whose type is xs:base64Binary or xs:hexBinary. The value of the attribute is the name of a IANA media type token (e.g., "text/xml; charset=utf-16"). This attribute specifies the media type of the content of an element on which it occurs. * a XML Schema annotation attribute (xmlmime:expectedMediaType) to indicate in XML Schema the expected media type(s) for an element content whose type is xs:base64Binary or xs:hexBinary. The XML Schema annotation, xmlmime:expectedMediaType, specifies the expected range of values for the xmlmime:contentType attribute and the expected range of types for the binary element content. -->8-- Does this change satisfy your concern? -Anish --
