The USVString part of the '''schema''' parameter for the validator api:
'''
Promise validate((USVString or RDFGraph) schema,
'''
could be a ShExC, ShExJ, ShExR, ... string. A mime type would be quite useful.
WebIDL is somewhat restricted in the datatypes available. URL parameters are commonly DOMString or USVString in other W3C Specs. Mime Types come in when interpreting the dereferenced result.
