Comment

xsl:attribute-set works hand in hand with the attribute "use-attribute-sets" (a space separated list if we need more than one attribute-set. In the above example xsl:attribute-set is not of much use, but if we have more templates also creating "img" elements in need of the same standard attributes, xsl:attribute-set could come in handy.
