Media type for RELAX NG Compact Syntax

I have written a servlet wrapper and a custom entity resolver for
Jing.[1] My code needs to decide whether to instantiate a compact syntax
schema reader or an XML syntax schema reader. I would very much like to
do the Right Thing. Currently, my code does the following;

1. If the HTTP Content-Type of the schema is
application/vnd.relax-ng.rnc, the schema is treated as a compact syntax
schema.

2. If the HTTP Content-Type of the schema is application/octet-stream,
the UA may guess. The implemented guess is that the schema is treated as
a compact syntax schema if its URL ends with ".rnc".

3. If the user has requested lax treatment of HTTP Content-Type and the
HTTP Content-Type is text/plain, the schema is treated as a compact
syntax schema if its URL ends with ".rnc".

In all cases, the charset parameter is supported for overriding the RNC
default UTF-16/UTF-8 sniffing. (I consider the charset parameter
harmful, but the RNC spec specifically blesses it.)

However, it seems the registration of application/vnd.relax-ng.rnc went
nowhere and the type is not official. Can anyone suggest a more correct
way of deciding if a schema acquired via HTTP should be treated as a
compact syntax schema?

(I'm inclined the consider the media type system in general and the
registration procedure in particular dysfunctional... It seems to me
that most .rng and .rnc schemas out there are served as text/plain.)
