Handling of addAttribute(null, ...)

Hi,

by reading the SAX sources, I come to the conclusion, that the empty string
("") is supposed for the default namespace. In other words, I must not use
something like

     AttributesImpl a;
     a.addAttribute(null, "value", "value", "CDATA", "");

(Probably the same holds true for ContentHandler.startElement() and
ContentHandler.endElement().) Fine for me.

However, if I do the above anyways, then I will receive an NPE in

     AttributesImpl.getValue(String, String)

regardless of the input. This is quite nasty, because the problems actual
source is elsewhere.

For that reason, I suggest adding checks for null to
AttributesImpl.addAttribute(). IMO this would enhance the libraries usability.


Regards,

Jochen
