m.room.message msgtypes.
Now that content referenced by the *m.audio*, *m.file*, *m.image*, and
*m.video* message types can be encrypted, the `url` field is required
*only* if the content is unencrypted. The "required" designation in the
event schemas (which prefixes the field description with "Required" in
bold in the generated HTML) is used to indicate fields which must always
be present, and this is no longer the case.

# is reserved by the swagger validator as a way to include partial content from a JSON object (eg: "#/path" would include {"test": true} from the object {"path":{"test":true}}). Instead of trying to convince the validator that it is wrong, we'll just use a different character.
Note that our rendering tools do not care about #-style references to objects. It's still somewhat worth changing the character though.
