I created this content package:
-> jcr_root -> tmp -> .content.xml:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:Folder"
property1="property 1"/>

<?xml version="1.0" encoding="UTF-8"?>
<workspaceFilter version="1.0">
<filter root="/tmp" mode="update" />
</workspaceFilter>
