I think this is a different id, i.e. it's a specific input method ID referenced in line 728 of this file. LGTM?

Just to make sure you know what I want to achieve: I want to use the same input method definition (rules/nb/nb-tildeforms.js) for two different language codes (nb, nn) with two different names (Tildemerket transliterasjon and Tildemerkt transliterasjon).
