Re: [xml-dev] Java 1.6 XMLStreamWriter and output indentation

Xerces is an XML parser, and Xalan is an XSLT processor.

Also, I don't think you are meant to use the "internal" interfaces...
there's likely to be a "public" one instead.

Hmm not sure I follow.  The reason for using a QName is to make is
easy to handle namespaces... for example, given the element:

<f:foo xmlns:f="foo_namespace">

and you want to process that using SAX, it's nice to do:

QName foo = new QName("foo_namespace", "foo", "f");

and then you can just compare QNames:

public void startElement(String uri, String localName, String name,
Attributes atts) throws SAXException {

  QName elem = new QName(uri, localName);

  if (elem.equals(foo)) {

and then if you need to write that element back out, you just want
give that QName to the writer, eg

writeStartElement(QName name)

rather than:

writeStartElement(String prefix, localName, namespaceURI)

...but that's easy enough to hide that behind an api.

It's nice to just define all of your elements and attributes as QNames
in one place, and have your parser and writer use them.
