L20n/Features/Public vs Private
From MozillaWiki
goal
separate entities and attributes that are locally defined by the localizer from the ones that should be available to the developer
example
<_brandName { nominative: "Firefox", genitive: "Firefoksa" } _gender: { mac: 'male', win: 'female' } accesskey: { mac: 'F', win: 'C'} > <about "About {{ _brandName.nominative }}"> <update[_brandName.._gender.win] { male: "{{ _brandName }} has been updated. The update took {{ $updateTime }} seconds." female: "{{ _brandName..accesskey.mac }}" }>
We decided to aim for using "_" in front of an entity name or attribute name to indicate that it's a local entity/attribute.
Those will be referenced the same way, but will not be available to the developer. (e.g. the developer cannot ask for _brandName.._gender here).
For l10n-dom, the local attributes (_gender) will not be copied as DOM attributes to the target node.
This will enable us to compare locales skipping local entries.
For computed calls, the syntax will look like this:
<foo "value" _gender: "c"> <title "Hello {{ foo.["_gender"] }}">
