The required conformance is stated the the i18n draft.

It has been agreed that the ALIGN attribute will mean what it says. Its
meaning will not be reversed under the influence of DIR=RTL.

However, the default for ALIGN may be affeted by the DIR of the element.
This has been left out of the spec.

BDO is specific to bidi, due to the mixture of RTL and LTR text in a single
element. Since I am not aware of a proposal to mix TTB and LTR in a single
element I don't think an extension is called for.
