I'll open a pull request with an additional reference to this paragraph, but I wonder if we can delete this bit of duplication completely?
I would be in favour of keeping it. It does not harm, it does not add any normative text, but may be helpful for RS implementers.

I would think this could be merged, @mattgarrish. If you do, could you also close w3c/epub-tests#173 without merge? |

As discussed in w3c/epub-tests#173, we have a redundant requirement on language processing for the
hreflangattribute.The internationalization section already defines that language and direction are obtained from resources, not information in the package document, and specifically calls out
hreflangas one case.This pull request just removes the redundant must for now, replacing it with a pointer to the overarching requirement, but I'm easily convinced we can drop the entire paragraph. It only seems to serve the purpose of reminding a developer of an existing requirement, but we don't repeat this for every element that has a language or direction property, so why here?
