From Martin Honnen on xsl-list:

Playing with the examples in http://www.w3.org/TR/xslt-30/#stream-examples I wonder whether the last example saying

------------------------------
Additional template rules could be added to process other elements and attributes in the same pass through the data: for example, to modify the value of a last-updated attribute (wherever it appears) to the current date and time, the following rule suffices:

<xsl:template match="@last-updated">
 <xsl:attribute name="last-updated" select="current-dateTime()"/>
</xsl:template>
-------------------------------

is not lacking a mode="#all" or mode="delete-ednotes" on the

 <xsl:template match="@last-updated">

as otherwise the template would not be applied to the document processed in a streaming way with the stylesheet presented earlier which does

<xsl:mode name="delete-ednotes" streamable="yes"
                               on-no-match="shallow-copy"/>
and

  <xsl:stream href="book.xml">
     <xsl:apply-templates mode="delete-ednotes"/>
  </xsl:stream>
