Remider: BIDI inter-label tests in -02

[Harald Alvestrand]

For all those of you who care about the bidi interlabel issue, the 
following text is in -02:

   o  The BIDI test MAY return failure if the BIDI rule is not satisfied
      by the label following the label that contains AL, AN or R in the
      domain name.  For all the reasons given above, it may be
      impossible to know the following label, but there seems no or
      negative value to allowing the BIDI test to succeed if the
      following label is known.  [[POSSIBLY CONTROVERSIAL]]

In the example Alireza gave, this would mean that the bidi test is 
allowed to fail on the <ALEF>.3.com domain name, but won't fail on the 
3.<ALEF>.com domain name - which would at least make sure the document 
gives guidance on the decision on which of the two names is going to be 
considered "valid" by whatever registry-specific or application-specific 
logic people implement to solve the problem elsewhere.

(As a personal preference, I would prefer to make it a SHOULD, or even a 
"MUST if the following label is known by the BIDI test" - but that did 
not seem to be the WG's consensus in Dublin, so that's not what the text 
says).

This editor needs WG direction on whether to either remove this bullet, 
reword this bullet, or remove the [[POSSIBLY CONTROVERSIAL]] tag.
