/**
* HHH-8364 discusses the use of <exclude-unlisted-classes> within Java SE environments. It was intended for Java EE
* only, but was probably supported in Java SE/Hibernate for user friendliness. If we are going to supports its use
* like that, the following should happen:
*
* Omitted == do scan
* <exclude-unlisted-classes /> == don't scan
* <exclude-unlisted-classes>false</exclude-unlisted-classes> == do scan
* <exclude-unlisted-classes>true</exclude-unlisted-classes> == don't scan
*
* This is true for both JPA 1 & 2. The "false" default in the JPA 1.0 XSD was a bug.
*
* Note that we're ignoring the XSD "true" default if the element is omitted. Due to the negation semantics, I thought
* it made more sense from a user standpoint.
