x-symbol in 15.4.18 Font Character Set of ODF 1.0?

What do you mean by "x-symbol"?  Do you mean any charset 
name that begins with "x-"?  Or, do you mean the string 
"x-symbol"?  

In both cases, I would argue that the schema should 
explicitly handle this special case adn that the 
current schema is not good enough for documentation.

Cheers,
