Description
For W3C credentials, the field value_type is defined as
String value determining the type of value of the claim. A non-exhaustive list of valid values defined by this specification are string, number, and image media types such as image/jpeg as defined in IANA media type registry for images (https://www.iana.org/assignments/media-types/media-types.xhtml#image).
I suppose that image/jpeg is a subtype of string and there is some encoding applied. If that's correct, both facts should be made explicit in the spec.

Start with the W3C credential definition of value_type and the IANA media type registry link cited in the issue. The work is complete when the specification clearly resolves whether image media types such as image/jpeg are strings and documents any required encoding.
