Too true, I'm sure many others can't wait to write template matches like
<xsl:template match="ipo:shipTo[. instance of element of type
ipo:USAddress]/ipo:state[. instance of element of type ipo:USState]" />
instead of
<xsl:template match="ipo:shipTo/ipo:state" />
because of the gains of schema aware processing
