Can git detect and manage source file's extensional attribute by command 'setfattr' ?

Hi ,
    I know that git can cope with file's chmod. But how about
setfattr? I have tried to set some extensional attribute with command
:
####
setfattr -n user.t1 -v 1 testfile.txt
####
It seems like git cannot detect it. So do I need some config option
for git? Or doesn't it have this feature?
    Thanks very much.
