Hi Santiago
I've read the updated section (3.7.3.b).
I admit I'll have to read few more times, it reads like a complex
theorem proof at the moment for me :-).
I'm not entirely sure what matching media type issues/ambiguities the
updated text is supposed to tackle,
from you message below:
text/* ? application/xml
Here is the one fragment from your earlier message:

Is it about dealing with cases like this one ?
If yes, then do you really think it is important to add some precision
in matching two types like text/* & application/xml ?
As I said I'm still trying to grasp what I've read, so please tell me,
would the updated text make it feasible for
text/* & application/xml be matched ?
Thanks, Sergey
