I have a question about XNI QName class.

Specifically, its "uri" field.

The documentation comment of this field is currently

>     /** 
>      * The URI to which the qname prefix is bound. This binding must be
>      * performed by a XML Namespaces aware processor.
>      */
>     public String uri;

When namespace is not used, for example

<?xml version="1.0"?>
<root />

It seems to me that this field is set to null, instead of "". Is this an
intended behavior?



AbstractSAXParser has the following statement:

>                 String uri = element.uri != null ? element.uri : fEmptySymbol;
>                 fContentHandler.endElement(uri, element.localpart,
>                                            element.rawname);

, which is consistent with the "noNS=null" hypothesis. But this can be
also interpreted as a precaution.
