RE: key definition

Okay, the following stylesheet works, but I would appreciate any
improvements. I would like to make the select statement as short
as possible (in characters that had to be typed) as i have to use
this construct many times in my application. This is the statement
that I would like to shorten up:

<xsl:key name="MyKey" match="/items/item/data"
  use="concat(@id,text())"/>

<xsl:template match="/">
 <xsl:for-each select="key('MyKey',concat('1','alpha'))/parent::*">
  <xsl:value-of select="data[@id='1']"/>,
  <xsl:value-of select="data[@id='2']"/><br/>
 </xsl:for-each>
 <hr/>
 <xsl:for-each select="key('MyKey',concat('2','gamma'))/parent::*">
  <xsl:value-of select="data[@id='1']"/>,
  <xsl:value-of select="data[@id='2']"/><br/>
 </xsl:for-each>
</xsl:template>
</xsl:stylesheet>
