[xsl] copy attribute question

[Garvin Riensche <g.riensche@xxxxxxx>]

Hello,

I am wondering why the context seems to be different in the following 
templates because I thought the output would be the same.

Input:
<a id="1"/>

Template 1:
<xsl:template match="a/@*">
  <aa>
    <xsl:copy/>
  </aa>
</xsl:template>

Template 2:
<xsl:template match="a">
  <xsl:for-each select="@*">
    <aa>
      <xsl:copy/>
    </aa>
  </xsl:for-each>
</xsl:template>

Template 1 doesn't produce any output and template 2 outputs:
<aa id="1"/>

Why doesn't Template 1 copy the attribute node to element <aa> like 
template 2?


regards,
Garvin
