I'm in the process of merging initial support for spoken MathML content into Orca. In doing so, I'll be adding a number of strings which need to be localized. However, there's still discussion about what Orca (and other screen readers) should say. Therefore, my commit will mark these strings for translation but will include translator notes that warn about the potential for the strings to change prior to the 3.18 release. Then they can base their decision about when to proceed accordingly.

I'm filing this bug so that I'll have something I can point to (in the translator notes, on the mailing list message I'll be sending to the i18n team) and they can use to be notified of the "all clear".
