I think we are going to have to enhance the Capability component to  
consider other factors in determining the media type besides mime type
Perhaps if we went straight from agent -> media type in the media  
type calculation with an optional attribute?

		<Client name="pocketpc" evalOrder="111" preferredMimeTypeID="text/ 
html" preferredMediaType='html-basic'>
...

I am not too enthusiastic about that solution as it requires  
additional model changes to support the optional preferredMediaType  
but Im really not coming up with a better solution
Propose that we review this implementation and consider reworking it  
for the 2.2 release as its not even clear to me why we have to go  
from client -> mimetype -> mediatype
That was leftover from J1 and I just modeled it the same way
For the 2.1.3 release, I don't want to make any schema changes
Do you need this for the 2.1.3 release? If yes, I propose finding a  
way to represent this relationship in the existing model

Hi David,

Thank you so much. Your comments gave me a clue.

Yeah, I agree with you. It's not a good idea to change the data model for the 2.1.3 release. It
would be better to review more and consider reworking it for the 2.2 release.

Yes, I need this for the 2.1.3 release to present some wireless-support features to my customers.
So, I'm considering to do the following things:
 - I'll create a valve named 'capabilityCustomizerValve', which would change the preferred
mediaType of the capabilityMap and the requestContext just after the capabilityValve finished.
 - This valve will decide the mediaType based on the given client-to-mediaType mappings as a
constructor argument. For example, "ie4ppc (client name) to html-basic (media type name)".
 - I'll add some seed data for Pocket IE. (mediaType and client)

Without data model changes, some configurations need to be added (e.g. client-to-mediaType
mappings), I think.
If my patch gets to be feasible, I'll let you know.

Thank you again!

Regards,

Woonsan
