An implNote was added to the DOM's package description in an attempt to 
document the JDK implementation's deviation
from the DOM specification. However, a further study showed that was incorrect 
because the XML specification did
include range [#x10000-#x10FFFF]. The Impl's interpretation was based on the 
clause "excluding the surrogate blocks".
The problem was it used Java char to determine it. Thus instead of excluding 
the surrogate blocks with codepoints
ranging from U+D800 to U+DBFF and U+DC00 to U+DFFF, it converted characters 
with a Java representation of a surrogate
pair into character references.
