I received the following mail from Mati Allouche (thanks, Mati!):

>1) I have reviewed your document http://www.ietf.org/internet-drafts/draft-duerst-iri-bis-01.txt and more particularly section 4 about Bidirectional IRIs, and I have a problem with example 9.  IMHO, the visual representation (Hebrew) should be: 
>http://ab.cd.ef/LK/JI%32/%31HG.html 
>and the visual representation (Arabic) should be: 
>http://ab.cd.ef/LK/JI32%/31%HG.html
>I suggest to check the proper result using one of the Bidi reference implementations that you can find on the Unicode site (or in the "Tools => Bidi Demo" menu item in the Unibook application). 

I have listed this as issue:
http://www.w3.org/International/iri-edit#bidi-fix-example-113

I will check this through. Looking at
http://www.w3.org/International/iri-edit/BidiExamples,
in general the green (displayed by the browser) and blue
(calculated by an implementation of mine) lines should match,
but for example 9, they indeed don't match.

>2) It might be appropriate to add example 11 as follows:

>  Logical representation: "http://ab.CDEFGH.123ij/kl/mn/op.html"
>  Visual representation: "http://ab.123.HGFEDCij/kl/mn/op.html"
>  Components consisting of numbers and  left-to-right characters are 
>   allowed, but these may interact with adjacent RTL components in ways 
>   that are not easy to predict.

I've listed this as:
http://www.w3.org/International/iri-edit#bidi-add-example-114
This is indeed a good point; for backwards compatibility reasons,
it is difficult to disallow such cases, but they'd indeed better
not exist.

Regards,    Martin.
