Mime subtype for a graphic, multimedia object, or piece of supplementary material.
Usage/Remarks
Values Best Practice
The source for this attribute’s values is the Internet Assigned Numbers Authority
(IANA).
Element Best Practice
Although this Tag Set cannot enforce it, the element <graphic> should be limited to still images. The element
<media> should be reserved for objects whose
@mime-subtype involves video, audio, moving
images, time-dependent graphic types, and other non-XML data types. Mimetypes and
subtypes
should be set accordingly but are not constrained by this Tag Set.
OPTIONAL on many elements; click for list and usage
