Why does attribute localName exist when namespace awareness is turned off?

When XMLDocumentFragmentScannerImpl scans elements it doesn't pass on any
localName or namespaceURI values, but for attributes it contains following
lines...

    protected void scanAttribute(XMLAttributes attributes) throws
IOException, XNIException {
        ...
        if (fNamespaces) {
            fEntityScanner.scanQName(fAttributeQName);
        }
        else {
            String name = fEntityScanner.scanName();
            fAttributeQName.setValues(null, name, name, null);
        }

The latter one kicks in and name is applied to both qName and localName.
According to <http://www.saxproject.org/namespaces.html> in my opinion the
localName should be empty. 

I've trusted so far localName being empty to imply that namespace awareness
is turned off. Luckily I can work around this problem in SAX relying on
element localName being empty instead.

Re: Why does attribute localName exist when namespace awareness is turned off?

Posted by Michael Glavassevich <mr...@ca.ibm.com>.
Might be a bug though there are certainly more direct ways of determining
namespace awareness. Specifically, checking the state of the SAX namespace
feature [1].

Thanks.
