You should try xsl:include and xsl:import first. See
  http://www.w3.org/TR/xslt#include
and
  http://www.w3.org/TR/xslt#import
If you really want aggregate style sheets, you'll have to use an
internal pipeline and a cocoon: redirection, something like
  <map:pipeline internal="yes">
    <map:match pattern="foobar.xsl"
      <map:aggregate element="dummy">
        <map:part src="file:///foo.xsl"/>
        <map:part src="file:///bar.xsl"/>
      </map:aggregate>
      <map:transform src="strip-dummy.xsl"/>
      <map:serialize name="xml"/>
    </map:match>
  </map:pipeline>
with the transformation in strip-dummy containing roughly
 <xsl:template match="dummy">
   <xsl:element name="stylesheet"
     namespace="http://www.w3.org/1999/XSL/Transform">
     <xsl:for-each select="xsl:stylesheet|xsl:transform">
       <xsl:copy-of select="."/>
     </xsl:for-each>
   </xsl:element>
 </xsl:template>
If you want to make more thorough manipulations with the aggregated
XSL, look at xsl:namespace-alias.
