How about

<xsl:key name="id" match="PAGE" use="@id" />
<xsl:key name="idref" match="Next" use="@id" />

<xsl:template match="Pages">
  <xsl:copy>
    <xsl:apply-templates select="PAGE[not(key('idref', @id))]" />
  </xsl:copy>
</xsl:template>

<xsl:template match="Next">
  <xsl:copy>
    <xsl:apply-templates select="key('id', @id)" />
  </xsl:copy>
</xsl:template>

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
