The comment() method reports the Comments as a char[] not a String.  It is similar
to the characters() or ignoreWhitespace(). 

Some of the SAX2 parsers report content of single element by multiple characters().

 ex) <elem>ABC

    ==> characters( "ABC\n", ?, 4);
        characters( "DEF", ?, 3);

I think it is good for parsing performance. When use same technique for reporting
comments, following problem is expected.

 After comment() was called twice, the application will not be able to discriminate
 ex2 from ex1.

 ex1) <!--ABC

    ==> comment( "ABC\n", ?, 4);
        comment( "DEF", ?, 3);

 ex2) <!--ABC

    ==> comment( "ABC\n", ?, 4);
        comment( "DEF", ?, 3);

I want to discriminate those, but since the SAX aims to be _simple_, sush
things is not siginificant?
