Here is a bit of the bean definition used by indexing to pick out the content from EML

<bean id="eml.origin" class="org.dataone.cn.indexer.parser.CommonRootSolrField" 
        p:multivalue="true" 
        p:root-ref="originRoot">
        <constructor-arg name="name" value="origin" />
    </bean>

    <bean id="originRoot" class="org.dataone.cn.indexer.parser.utility.RootElement" 
        p:name="origin" 
        p:xPath="//dataset/creator" 
        p:template="[individualName]||[organizationName]">
        <property name="leafs"><list><ref bean="organizationNameLeaf"/></list></property>
        <property name="subRoots"><list><ref bean="individualNameRoot" /></list></property>
    </bean>

Spaces aren't really sufficient as a solution, and there are a lot of references fields in EML. We probably need to contribute a fix for this if Skye is not going to fix it for DataONE.

Skye said that the sax parser is used to parse those information. This change may require to use DOM parser. It is a big change.

Even with a SAX parser, the implementation could keep track of all elements with "id" attributes and anytime a "references" element is encountered, substitute with that node. The tricky part would be when we encounter a references element before the actual element that declares the id -- would have to track the references that are unfulfilled and fill them in when we actually get to the id elements.
