- 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.
