incorrect double quote escape (typo)

[GoogleCodeExporter]

In XMLWriter.m
The escape sequence for quote is

written as 
                        [self write:@"&qout;"];
Where it should be:
                        [self write:@"""];


See
http://www.w3.org/TR/xml11/

To allow attribute values to contain both single and double quotes, the 
apostrophe or single-quote character (') may be represented as "'", and 
the double-quote character (") as """.
