Looks awesome!
Small thing left: export daLocale in srx/index.ts
Or system.js users will not be able to import it :(

[perhp]

daLocale is exported from src/locale.ts which is exported from src/index.ts by export * from './locale';.
That should do it? :)

[valorkin]

Indeed, I forgot that I ended up with this hack for system.js

Tested, looks good
