I'm certainly no Relax expert, but on the face of it is does *NOT* 
sound reasonable. In general XML and Unicode processing, one *MUST* 
handle characters with code points beyond U+FFFF. They are not 
optional.  This is true even if your programming language (Java 
perhaps?) has inadequate support for them.

Just possibly, if this only applies to characters in XML names, not 
content or attribute values, and only XML 1.0 is supported (Not XML 
1.1) then this may be reasonable. Otherwise it's clearly not.
