The special case conversion:domain_template "[.]" is equivalent to a conversion:PrimaryKeyEnhancement (the latter is deprecated).

Ontology

domain_templates can not be conversion:bundled_by any bundle.

conversion:domain_template 
   rdfs:domain [ owl:onProperty conversion:bundled_by; owl:cardinality 0; a owl:Restriction ] .
