XML Schema support in Xerces SAX1?

[William Sinclair <william.sinclair@provato.com>]

I'm having trouble getting XML Schema validation to work under Xerces
1.4.1. We are currently using the deprecated SAXParser and
DocumentHandler classes from SAX1. There are a couple of things in the
release notes that make me think I can't use XML Schema with SAX1,
including no support for namespaces. But I can't find anything about it
on the Xerces site. Can anyone confirm or deny this for me? If it can
work, any tips on getting it to?
Here's the code I have currently:

SAXParser parser = new SAXParser();
parser.setDocumentHandler(handler);
parser.parse(input);

where handler extends HandlerBase and only overrides startElement() and
endElement().

Anything else I need to do?

Tanks for any help or info,
Wil
