7.6 Content Types

The Open Packaging Conventions standard requires that the file name extensions of the files contained in a Descriptor are registered in the “[Content_Types].xml” file. Only file name extensions used in a Descriptor shall be present in the “[Content_Types].xml” file of the Descriptor.

A list of IANA registered content types is given at: https://www.iana.org/assignments/media-types/media-types.xhtml.

Table 2 gives some examples of file name extension content types.

The use of vendor-specific file name extensions is allowed. The vendor-specific file name extensions and content types may or may not be registered with IANA.
