Eric,<br><br>in the various email exchanges from Arabic working group(s), I came away with the impression that a safer and apparently acceptable policy would be to prohibit mixing of any of these three in the same label. That is plainly more stringent than your proposal but I did not get the sense that the working groups whose email exchanges I was privileged to see felt they needed to mix any of these together. <br>

Vint, John, Paf, All,<br>
<br>
On the question of what to do about the code points in the ranges<br>
<br>
U+0030..U+0039,<br>
U+0660..U+0669,<br>
U+06F0..U+06F9,<br>
<br>
I think that allowing only the first range is incorrect.<br>
<br>
I think that allowing all three ranges is correct if a mechanism for equivalency exists.<br>
<br>
Assuming that no equivalence mechanism exists, for whatever rational, I think that allowing the first range, and only one of the second two ranges, is sufficient.<br>
<br>
Outside of the protocol, registries are free to implement a registry-local policy, which may restrict code points in a label to one range only, or one of two ranges, where one is in the U+0030..U+0039 range, but not both of the ranges U+0660..U+0669 and U+06F0..U+06F9.<br>
<br>
As I mentioned yesterday, and as the jabber scribe correctly summarized:<br>
<br>
<a href="mailto:ajsaf@jabber.org" target="_blank">ajsaf@jabber.org</a> Eric: reject latin-only<br>
<a href="mailto:ajsaf@jabber.org" target="_blank">ajsaf@jabber.org</a> accept proposal for no mix between extended and non-extended<br>
<a href="mailto:ajsaf@jabber.org" target="_blank">ajsaf@jabber.org</a> but overboard to go further<br>
<br>
There are, as John rebutted, buggy input methods, but that can't be controlling.<br><font color="#888888">
