Will there be note in the online version of the technical report to
mention this? There may be poor developers just like us ;) who won't know
that these recommendations will make their application nonconforming.

In our case, we read and reread the spec many times, even by developers
who had not heard about the Unicode bidi before, because we simply thought
that it's our implementation or interpretation bug.
