Martin, the middle dot is a DISALLOWED codepoint due to the rules we  
have agreed to, that refer to the properties Unicode Consortium has  
decided upon. What we try to do now is to understand under what  
circumstances (if any) IETF should override the decision made by UTC  
to treat it as a punctuation.

We have made such decisions for other codepoints, but the charter say  
we have to be careful.

So I do not see the current discussion be strange at all.

We even add contect rules as exceptions for codepoints that where  
supposed to be PVALID if we "just" took the rules from UTC straight  
out of the box!
