I love the idea.  This is certainly a great improvement.

I have one question.  Is U+30FB (Katakana Middle Dot) a name character 
in Unicode 3.0?  I had a look at the WWW site of the Unicode Consortium, 
but I could not find any information about it.

Omission of this character in Unicode (and thus XML) is very serious.  This 
character is so common.  It is a very bad error of Unicode nameing rule.  
In a meeting of Japanese Standardization Association, I was asked why this 
character is not allowed as a name character in XML.  Some users asked the 
same question in an XML mailing list in Japan.  This character is needed 
very very badly.

I have spoken with some members of UTC and repeatedly asked them to make this 
change.  But I am still not sure if Unicode 3.0 allows this character as a 
name character. 

The second version of ISO TR 10176:1998 (Guideline for preparation of programming 
language) also has a rule for name characters.  This rule allows U+30FB as a 
name character.

In the property list of Unicode, U+30FB is classified as hyphens.  

Property dump for: 0x20000800 (Hyphen)

002D
00AD
058A
1806
2010..2011  (2 chars)
30FB
FE63
FF0D
FF65

If we cannot handle U+30FB as an exception, we can allow all these characters 
except FE63, FF0D, FF65.
