/**
* Utility method that can be used by classes in this package. It creates a new specification for
* OWL DL models that are stored in memory and do no additional entailment reasoning, i.e., the
* reasoner is initially set <code>null</code>.
*
* <p>Furthermore, the model specification delegates to the global <tt> OntDocumentManager</tt>
* provided by Jena. Consequently, all the global settings are used, such as alternative paths,
* prefix mappings, ignored ontologies, and the global cache (if not disabled). Note that
* modifying the internal state of the document manager may cause inferences in multithreaded
* environments, e.g., modifying the set of ignored ontologies by one thread while another thread
* reads the set at the same time.
*
* @return A new ontology model specification.
