Missing prefix in examples

[brettz9]

Within section 2.5 of http://www.w3.org/TR/XHTMLplusSMIL , shouldn't the
2 examples with <animateMotion/> at least include a prefix like "smil:",
since they are being included within an XHTML <div/> and since the
earlier example defined a namespace for "smil:"?

thanks,
Brett
