I am really glad you understand me.

I am not really happy with this. First of all, there is no country
code ur for urdu. xkeyboard-config is using iso3166 (except for very
few very special cases). So could you please use the suitable country?
Also, the acceptable group name format is
"{country name}" - for default group
"{country name} - {variant description}" for non-default groups. See
other symbols/* files for examples.

Cheers,

Sergey
