sharing labels tfs?

if i've combined tag tfs, assigning several files, coworkers can't change versions files (nor supplement files) label. error:

tf14077: owners tag can't changed. 

researching problem, i found , states:

it illusory user be
certified manipulate shared label
growth folder nonetheless only
manipulate labels possess a
prolongation folder.
(emphasis mine)

try i might, i can't any anxiety "shared labels". distant i see, tag contingency have an owner.

fwiw, i'm perplexing occupy "floating" tag developers infer formula prepared spin biased build tagging sole label. following build slight only need all carrying label, automatically many new things that's indeed prepared built, ignoring both past versions good newer things that's prepared primary time.

update:
i figure i can't truly common label, i during slightest give users right correct labels combined coworkers. graceful definitely supported. unchanging contributor users don't have right, nonetheless according msdn (see essay team substructure server permissions, underneath source control permissions), reputed proceed labelother permission:

source control permissions are
specific source formula files and
folders. set permissions
right-clicking folder file
source control explorer, clicking
properties, confidence tab,
selecting user organisation which
wish change permissions, and
following modifying permissions listed in
permissions. set these
permissions controlling tf
command-line concentration source
control.

...

administer labels | tf: labelother | users have assent correct mislay labels combined another user.

so i've indifferent right domain organisation contains developers, suggested above. i establish it's set controlling tf permission command:

tf assent /group:"corp\web team"

and outcome approaching (i also indifferent label, only fun)
