What's the rationale for this?
I am not sure but OuterXml/InnerXml never pay attention to the
PreserveWhitespace property, neither on reading nor on setting.
Here is an example showing that for reading OuterXml and comparing it to
the Save method:
XmlDocument doc = new XmlDocument();
doc.LoadXml("<root><foo><bar>baz</bar></foo></root>");
doc.Save(Console.Out);
Console.WriteLine();
Console.WriteLine(doc.OuterXml);
doc.PreserveWhitespace = true;
doc.Save(Console.Out);
Console.WriteLine();
Console.WriteLine(doc.OuterXml);
Output is
<?xml version="1.0" encoding="ibm850"?>
<root>
<foo>
<bar>baz</bar>
</foo>
</root>
<root><foo><bar>baz</bar></foo></root>
<?xml version="1.0"
encoding="ibm850"?><root><foo><bar>baz</bar></foo></root>
<root><foo><bar>baz</bar></foo></root>
