<!-- Nested Pages Hierarchy -->

<!-- When displaying the page hierarchy (e.g. using the tree widget) we need to get information from
both the documents table and the spaces table. Each of these tables contains some information that is
not found on the other. The documents table contains the terminal pages while the spaces table contains
the "empty" spaces (no direct terminal child pages). In order to get all the needed information we need
to perform a union or an outer join (between unrelated Hibernate entities). The Hibernate version we
use doesn't support either (HHH-1050 and HHH-16) so we define a new entity XWikiPage that is mapped to
a SQL query rather than to an existing table. The SQL query can be overwritten for specific databases
if needed. See XWIKI-13468. In the future we could merge the documents and spaces tables into a single

<!-- Nested Pages Hierarchy -->
<!-- -->
<!-- When displaying the page hierarchy (e.g. using the tree widget) we need to get information from
both the documents table and the spaces table. Each of these tables contains some information that is
not found on the other. The documents table contains the terminal pages while the spaces table contains
the "empty" spaces (no direct terminal child pages). In order to get all the needed information we need
to perform a union or an outer join (between unrelated Hibernate entities). The Hibernate version we
use doesn't support either (HHH-1050 and HHH-16) so we define a new entity XWikiPage that is mapped to
a SQL query rather than to an existing table. The SQL query can be overwritten for specific databases
if needed. See XWIKI-13468. In the future we could merge the documents and spaces tables into a single
one (the pages table) -->

<!-- This entity is used to represent the Nested Spaces hierarchy, which we don't use in practice
(we normally use the Nested Pages hierarchy instead) but the Document Tree has an option to display it
so we keep this entity for backward compatibility. Even though the page and the space entities are distinct
in this hierarchy, a space can have both page and space children so we still need to query them together
in order to support sort and pagination. -->
