The link types are dual-purpose. The digital publishing industry wants to use the dpub ARIA semantics which originated from EPUB structural semantics which originated from DAISY book readers. The dpub industry would use these properties to drive styling, etc. of books. If these were localized that would make this very challenging. 


… So, these aria properties are designed to allow the digital publisher to apply the structural semantics they need to drive the authoring process while getting accessibility for free.

I don’t know if you have been following the aria discussion but we are looking at introducing an aria-linktype for the different types of links that are in EPUB so that we can still use things like AXLink and not proliferate link roles.
