Since XML 1.0 does not require namespace support, it is possible for
a parser to be XML-conformant without supporting namespaces -- in that
case, it would always set the URI part of the name to null.
This leads to another thought -- that we probably need some kind of a
hook for requesting and/or querying parser features. This issue came
up before during the initial SAX 1.0 design. Something like the
following might be appropriate:
package org.xml.sax;
public interface Parser {
...
public boolean hasFeature (String featureName);
public boolean requestFeature (String featureName, boolean status);
}
It is important to note that with such an approach, there would have
to be a registry of feature names in addition to the SAX interface.
Here's how you could use this interface:
if (!parser.requestFeature("org.xml.sax.validation", true) ||
!parser.requestFeature("org.xml.sax.namespaces", false)) {
throw new MyException("Cannot activate validation without namespaces.");
}
The details remain to be worked out.
All the best,
David
