* Small helper class that lazily loads DOM and SAX reader and keep them for fast use afterwards.
* Small helper class that lazily loads DOM factory and keep them for fast use afterwards.
*
* This was part of Hibernate ORM core, but moved into the testsuite helpers to not expose
* access to the dom4j types. It's also used by Hibernate Envers, so we will need two copies
* until Envers is able to remove its reliance on dom4j.
* This was part of Hibernate ORM core, but is used exclusively by Hibernate Envers now:
* keep visibility lower so to not expose Dom4j to public API.
* The rest of Hibernate uses StAX now for XML processing. See {@link org.hibernate.boot.jaxb.internal.stax}
