The closest there is is a "Public Identifier", and the only things that the spec says about it are (a) that certain spaces within it are insignificant, and (b) that the processor can try and convert it to a URI (but it doesn't say how). For the perceptive reader, the choice of name for the metasymbol suggests that the authors were thinking of some kind of global namespace, and the examples of Public Identifiers suggest they were thinking of some kind of analogy with a similar namespace used in SGML. But this is reading between the lines of the standard. It's actually even easier to write a Public Identifier for a MIME type, if I can choose I can call it "image/gif", or even "fred".
