Proposed Disposition of DIS 29500 Comment US-0150 (Modified: 2008-01-04) Agreed; just as there is a content type available for files included within the document package (using the content type item defined in Part 2), there should be a way to specify a content type when using the audio element to link to external audio content. As well, the list of audio codecs provided in Part 1 should be referenced from this location. The following changes will be made to the specification: Part 4, §5.1.3.2, page 3,292, line 26, a new attribute will be added Attributes Description contentType (Content Type of Linked Audio File) Specifies the content type for the external file that is referenced by this element. Content types define a media type, a subtype, and an optional set of parameters, as defined in Part 2, §8.1.2. If a rendering application cannot process external content of the content type specified, then the specified content can be ignored. [Note: A list of suggested audio types is provided in Part 1, §15.2.2. end note] If this attribute is omitted, application should attempt to determine the content type by reading the contents of the relationship’s target. The possible values for this attribute are defined by the XML Schema string datatype. Part 4, §5.1.3.2, page 3,293, after line 6 The following XML Schema fragment defines the contents of this element: <complexType name="CT_AudioFile"> <sequence> <element name="extLst" type="CT_OfficeArtExtensionList" minOccurs="0" maxOccurs="1"/> </sequence> <attribute ref="r:link" use="required"/> <attribute name="contentType" type="xsd:string" use="optional"/> </complexType> Similar Comments: BR-0052 , CO-0219 , FR-0357 , GB-0308 , PT-0104 ,
