Done.

Do we ever use this for anything?

[Joao da Silva, 2013/11/07 20:27:27]

It's what the PolicyStatisticsCollector samples for UMA. histograms.xml then
maps these IDs to the policy names for diplaying

[bartfab (slow), 2013/11/05 18:18:33]

Could you drop the part "to be downloaded"? As Mattias pointed out in our
earliest discussions about external policy data, we may want to support
platform-specific references in the future that do not require downloading, e.g.
UNC paths.

[Joao da Silva, 2013/11/07 20:27:27]

Done.

Nice mocking mechanism.

Daniel and I have remarked how the component refactoring is improving the code
in other ways. This was another choice "forced" by the DEPS constrains of the
component.
