I have had exactly this in my parser interface for a while, namely a
CharacterData interface.  It has methods for retrieving the content as a
character arrays, Strings, normalized character arrays, normalized strings, and
support for direct parsing of characters into primitive values like ints,
booleans, and floats (this support is there so you are not forced to create a new
String object just to parse content into a number with methods like
Integer.parseInt(String s)).

Not sure if this would be in the realm of SAX since SAX is supposed to be a
Simple API for XML, but some sort of character data interface with a lazy data
model behind it that at least supports new character arrays, copying, strings,
and normalized content would not be such a bad idea.
