You are correct, this is a typo in the Protocol document. The typo has been fixed in the editor's draft of the document and will be included as the document moves towards recommendation. We also verified that the protocol validator being used by the working group to verify implementation conformance already uses the correct media type (indicating that implementors did not copy this typo).
