mime-subtype Mime Subtype (deprecated)

Mime subtype for a graphic, multimedia object, or piece of supplementary material.

Usage/Remarks

The source for this attribute’s values is the Internet Assigned Numbers Authority (IANA).

Combine @mime-subtype into @mimetype

Avoid using @mime-subtype and @mimetype as separate attributes. Instead, combine mimetype and mime-subtype values separated by a slash inside @mimetype (e.g., @mimetype="application/excel"). IANA documentation refers to these combined mimetypes as “media-type”.
Prior to JATS version 1.4d1 and BITS version 2.1 BITS, the mimetype and subtype attributes were coded separately (mimetype="application" mime-subtype="excel"). For backwards compatibility, this usage will still be valid JATS/BITS, although precombined mimetypes are now preferred.
