64 * @c xsl:apply-templates.
66 * Note that ApplyTemplate isn't named ApplyTemplates. The reason for this
67 * is that ApplyTemplate doesn't do the iteration part. An @c
68 * <xsl:apply-templates/> instruction is rewritten into:
71 * child::node/() map apply-template()
74 * Hence, this expression requires a focus, although it can consist of
