For 2.0 only the <xsl:element name="{local-name}"> can be replaced
by <xsl:copy copy-namespaces="no">

Well I can say it worked for moving things from the null namespace
to the desired one without contradicting Ken,

xsl:copy won't change the namespace of the copied element so this
instruction must always have been masked by higher priority templates if
the namespaces were changed.
