-      TODO: <a href="https://golang.org/cl/203417">https://golang.org/cl/203417</a>: fix reserved namespace check to be case-insensitive
+      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.
