Description Michael Dyck 2014-03-05 00:23:04 UTC 
In 8.4.2 "Data model",
in the algorithm for 'focus chain',
steps 4 and 5 have the structure:

    4. If A, append ...

       Otherwise, if B, append ...

    5. Otherwise, if C, ...

       Otherwise, if D, ...

       Otherwise, if E, ...

I'm concerned about the "Otherwise" that begins step 5.

It's unclear if it means:
    if A is not true
or instead:
    if A is not true and B is not true
Both interpretations are odd, for different reasons.

I wonder if it shouldn't be there at all. That is, should step 5 begin with
    5. If current object is a dialog object ...
?

Checked in as WHATWG revision r8524.

Yeah, that first "Otherwise" in step 5 is bogus. Good catch.
