[NOTE]
====
The `exclude-unlisted-classes` element always indicates that __no__ scanning for
annotated entity classes is supposed to occur, in order to support the
`<exclude-unlisted-classes/>` shortcut. This is in line with the JPA specification,
which suggests that shortcut, but unfortunately is in conflict with the JPA XSD, which
implies `false` for that shortcut. Consequently, `<exclude-unlisted-classes> false
</exclude-unlisted-classes/>` is not supported. Simply omit the
`exclude-unlisted-classes` element if you want entity class scanning to occur.
The `<exclude-unlisted-classes/>` shortcut indicates that __no__ scanning for
annotated entity classes is supposed to occur. An explicit 'true' value specified -
`<exclude-unlisted-classes>true</exclude-unlisted-classes/>` - also means no scan.
`<exclude-unlisted-classes>false</exclude-unlisted-classes/>` does trigger a scan;
however, it is recommended to simply omit the `exclude-unlisted-classes` element
if you want entity class scanning to occur.
