Like this:

<xsl:variable name="temp-tree-1">
  <xsl:apply-templates select="/" mode="phase1"/>
</xsl:variable>

<xsl:variable name="temp-tree-2">
  <xsl:apply-templates select="xx:node-set($temp-tree-1)" mode="phase2"/>
</xsl:variable>

<xsl:template match="/">
  <xsl:apply-templates select="xx:node-set($temp-tree-2)" mode="phase3"/>
</xsl:template>

The xx:node-set() is an extension function supplied by your favourite
vendor.
