You could build a joint grouping key out of the attribute values:

  <xsl:template match="RefMaterial">
    <RefMaterial>
      <xsl:apply-templates select="@*"/>
      <xsl:for-each-group select="Application" 
group-by="string-join((@Subst_ID, @ApplCode), '__')">
        <xsl:copy-of select="." /><!-- first group item -->
      </xsl:for-each-group>
    </RefMaterial>
  </xsl:template>
