I don't understand what you mean. "methods" field in "usrloc" table just means 
allowed receiving methods for that the device, but not which methods it can 
generate.

For example, Twinkle 1.1 that support presence sends this "Allow" header:

Allow: INVITE,ACK,BYE,CANCEL,OPTIONS,PRACK,REFER,NOTIFY,SUBSCRIBE,INFO,MESSAGE

And Linksys PAP2, that doesn't support presence, sends this one:

Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER

Maybe devices which send PUBLISH allow always a received SUBSCRIBE, but 
having "SUBSCRIBE" in "Allow" header dones't mean supporting PUBLISH. Does 
it?

Regards.
