Out of curiosity: Why are the types placed in a target separate from
autofill_content_mojo_bindings_mojom? 

[leonhsl(Using Gerrit), 2016/05/24 06:38:20]

Because in future these autofill types would also be referenced by mojom files
from //components/password_manager/content/public/interfaces which I'm planning
to create in follow up CLs, so I think we'd better put autofill types in a
separate target to avoid password_manager interfaces depending on autofill
interfaces ;-)
