Are there any possible other elements involved other than that 
"mainterm" element before the "link" and "sublink"? If not and if you 
can use XSLT 2 or 3 then use


    <xsl:template match="ani:descriptor">
        <xsl:copy>
            <xsl:copy-of select="@*, ani:mainterm"/>
            <xsl:for-each-group select="* except mainterm" 
group-starting-with="ani:link">
               <xsl:sort select="."/>
               <xsl:copy-of select="."/>
               <xsl:perform-sort select="current-group() except .">
                  <xsl:sort select="."/>
               </xsl:perform-sort>
            </xsl:for-each-group>
        </xsl:copy>
    </xsl:template>
