was going to save this for the f2f but.....
T.Create() and T.Delete() are used to create/delete entire resources - 
using it to do something else (like _not_ creating/deleting a resource) 
would violate the extensibility rules of Transfer where it talks about 
extensions spec not contradicting the base spec.  The way to think about 
ws-frag is that it defines the "instructions" for how to get the Put done. 
 Put is still updating the resource, its just instead of doing a blind XML 
copy-n-replace, we're passing in an instruction for how to do the update 
but the semantics/purpose of the operation is still the same.

thanks

I have a question about the introduction of 'mode' in fragment PUT
mode has three different values:
http://www.w3.org/2009/02/ws-fra/Modes/Replace
http://www.w3.org/2009/02/ws-fra/Modes/Insert
and
http://www.w3.org/2009/02/ws-fra/Modes/Remove

Put+Remove sounds awfully like a Delete, and Put+Insert looks also awfully 

like a Create. (and Put+Replace looks like... a Put)
So why adding another axis of extensibility to duplicate what's already 
there?
