Org.xml.sax, Interface ContentHandler

Question

Hi all,
In the above interface, we have startElement method. The API says:
"This event allows up to three name components for each element:
the Namespace URI;
the local name; and
the qualified (prefixed) name.
Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes properties:
the Namespace URI and local name are required when the namespaces property is true (the default), and are optional when the namespaces property is false (if one is specified, both must be);
the qualified name is required when the namespace-prefixes property is true, and is optional when the namespace-prefixes property is false (the default). "
Can sb. please tell me:
- what does it mean when it says: "namespaces property is true and when it's false"?
- what's the difference bet. the local name; and the qualified (prefixed) name?
Thank you all. Any help is greatly appreciated.

For the first part, I think thiere is a type in the API, and it should read "feature" not "property", In the code you would have something likeparser.setFeature("http://xml.org/sax/features/namespaces", true);
[/code[
I got this from http://xml.apache.org/xerces2-j/features.html
As for local vs. qualified name - it escapes me for the moment
