-      The encoder has always taken care to avoid using namespace prefixes beginning with
-      <code>xml</code>,
-      which are reserved by the XML specification.
-      Now, following the specification more closely,
-      that check is case-insensitive, so that prefixes beginning with
-      <code>XML</code>, <code>XmL</code>,
-      and so on are also avoided.
