# Checks whether there are new attributes in models that are currently being exported as part of the
# project Import/Export feature.
# If there are new attributes, these will have to either be added to this spec in case we want them
# to be included as part of the export, or blacklist them using the import_export.yml configuration file.
# Likewise, new models added to import_export.yml, will need to be added with their correspondent attributes
# to this spec.
