What does this code segment do?

<xsl:template match="@* | text() | comment() |
processing-instruction()"><!--  -->
  <xsl:copy/><!-- Creates a copy of the current node (without child nodes
and attributes) -->
</xsl:template>
</xsl:stylesheet>

It has no mode so im not sure how it is called by the other templates. If it
applies for all attributes, text, cmments and processing-instructions in the
souce document then what keeps it from over writing the work of the other
templates?
