It depends on how you are supposed to know which xml pieces to
concatenate.  Assuming there is some way to know that beforehand, I
would create a driver file and run the transform against it instead.
Something like this -

driver.xml

<pieces>
 <piece src='file:///piece1.xml'/>
 <piece src='file:///piece2.xml'/>
...
</pieces>

aggregate.xsl

<xsl:stylesheet .....>
<xsl:template match='/pieces'>
<wrapper-element>
   <xsl:for-each select='piece'>
      <xsl:copy-of select='document(@src)'/>
   </xsl:for-each>
</wrapper-element>
</xsl:template>
</xsl:stylesheet>

This is simple and easy to maintain, and very clear as to what it is
doing.
