Gary,
You can use the sample xml/xsl files that come with any Xalan
distribution
and you'll get the same errors.

Subject: Re: Exception using DOMResult
Your input DOM is fine. The problem is with the output. DOM only
allows one Element below the Document Node. This is called the Document
Element. It looks like you're trying to ask Xalan to create a DOM with
more than one Document Element (or possibly a text Node) below the
Document.
If you're having problems diagnosing the error after this explanation,
please attach the XML produced by your StreamResult and we'll have a
look.
