StringnamespaceURINamespace URI to use for the root element for the document.
StringqualifiedNameName to use for the root element of the document.
DocumentTypedoctypeDocumentType object to use for this document. (optional)

For examples, see the quirksmode test page:

http://www.quirksmode.org/dom/tests/implementation.html

Remarks
Creates a new document, which can subsequently be used to add new nodes and other content. createDocument takes arguments defining what the name of the document (or root) element will be. Additionally it can take an optional DocumentType object that can be used to define a logical <!DOCTYPE> block for this document.
Throws
Raises an INVALID_CHARACTER_ERR error if the specified target contains illegal characers.
Raises a NAMESPACE_ERR error if qualifiedName is incorrectly formed, has a namespace prefix or is set to xml when the namespaceURI is not "http://www.w3.org/XML/1998/namespace".
Raises a WRONG_DOCUMENT_ERR error if the supplied doctype has already been used by a different document.
