ODL client does not support edit hello capability

I have a netconf server which required to commit the configuration change by operation <commit> or <close-session>. I found which is not supported in ODL.

in this situation, netconf server expected ODL to declare a private capability to automatically commit for each operations.

But the capability of ODL is hard-code, can not be edit or append by configuration files.

Can you support to edit or append the new capability by configuration files?
