[Vortex] No access to message MIME headers?

[Jens Alfke]

I can't find any way to use the Vortex API to get or set arbitrary  
MIME headers of a frame -- only the Content-Type and Content-Transfer- 
Encoding are accessible.

On the sending side: It looks like the internal function  
__vortex_channel_get_mime_headers creates the headers for an outgoing  
message. It allows each channel to set a single content type and  
encoding, but doesn't allow these to be set per-message, and doesn't  
create any other headers.

On the receiving side: VortexFrame doesn't store the full headers,  
only the content type and transfer encoding, so there's no way to get  
the others. Even vortex_frame_get_raw_frame, which I thought would let  
me parse out the headers myself, doesn't return the original frame  
received, but builds up the frame data from its pre-parsed state  
(minus the extra headers.)

Did I miss something, or is Vortex really missing support for this  
part of the BEEP protocol?
