Well, MathML is clearly a special case, it seems very unlikely that any 
other application domain in the history of the universe will have a 
comparable requirement for the use of characters that are not on any 
keyboard and do not have any input method.

Having said that, let's grant that some languages will want to have 
their own names for funny characters; it is still not clear that when 
you're defining a language, the mechanism you use to constrain the 
logical structure is the right one to use to give names to such 
characters. -Tim
