There are two ways. One is to use temporary trees (result tree fragments)
and the node-set() extension function:

<xsl:variable name="temp">
  <xsl:apply-templates select="/" mode="phase1"/>
</xsl:variable>

<xsl:template match="/">
  <xsl:apply-templates select="xx:node-set($temp)" mode="phase2"/>
</xsl:template>

The other is to control it from the API. The JAXP 1.1 Java API has
particularly neat ways of doing chaining by passing data from one stylesheet
to the next as a SAX event stream.

(There's a third way, with saxon, the saxon:next-in-chain extension).
