Writing any text content, including string.Empty, puts that element into mixed content mode. Child elements do not inherit this "mixed" mode status. A child element of a "mixed" element will do indenting, unless it is also contains "mixed" content. Element content (http://www.w3.org/TR/1998/REC-xml-19980210#sec-element-content) and mixed content (http://www.w3.org/TR/1998/REC-xml-19980210#sec-mixed-content) are defined according to the XML 1.0 definitions of these terms.
