Returns a read-only DOM node containing the <Schema> element.
Set objXMLDOMNode = objXMLDOMSchemaCol.get(namespaceURI)
HRESULT get(BSTR namespaceURI, IXMLDOMNode ** pNode);
This may be any string that can be used in an xmlns attribute, but it cannot contain entity references. The same white space normalization that occurs on the xmlns attribute also occurs on this argument (that is, leading and trailing white space is trimmed, new lines are converted to spaces, and multiple adjacent white space characters are collapsed into one space).
This will not necessarily be the same document object provided by the add method, because the add method may have copied the schema. For inline schemas, this will apply directly to the <Schema> node embedded within the document.
