# bq. Gamertags can only contain letters, numbers, and spaces, and can't begin
# with a number.
#
# In addition we discovered that they have no minimum length but are no more
# than 15 characters, and also cannot start with a space.

# The following error message keys are used to localize invalid screen names.
#
# | @xbox_too_long@ | Gamertag is over 15 characters. |
# | @xbox_invalid_chars@ | Gamertag contains invalid characters. |
# | @xbox_invalid_first_char@ | Gamertag doesn't start with a letter. |
