[JCR Importer] generated xml triggers a SAXParseException

[jckautzmann]

The following generated xml triggers an xml Exception when the package is installed in AEM:

keywords=\"[Automation,mRNA,Precision & Genomic Medicine,Monoclonal Antibodies]\" topics=\"Automation,mRNA,Precision & Genomic Medicine,Monoclonal Antibodies\"

Error in AEM:

Caused by: org.xml.sax.SAXParseException: The entity name must immediately follow the '&' in the entity reference.
    at java.xml/com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:204)

'& ' should be escaped: replacing '& ' with '& ' fixes the error.
