org.jboss.util.xml.DOMWriter.printInternal() skips the DOCUMENT_NODE

Somewhere along the line the xml property editors got changed such that the tests break.

Probably for pretty printing? So I'm assigning this to Thomas, to validate and apply to JBoss4 as appropriate.

It doesn't look like it changed the meaning of the xml,
nor does it change what was attempted to be tested according to the comment.

I've fixed the tests as follows in head:

// Comments can appear outside of a document
String s = "<!-- document --><doc name='whatever'/>";
// WAS String s = "<!-- document --><doc name=\"whatever\"></doc>";

// Test whitespace preservation
s = "<element>\n\n<e2/> testing\n\n</element>";
// WAS s = "<element>\n\n<e2></e2> testing\n\n</element>";
