+ This is an XML Schema description of the format
+ output by MediaWiki's Special:Export system.
+
+ Version 0.2 adds optional basic file upload info support,
+ which is used by our OAI export/import submodule.
+
+ Version 0.3 adds some site configuration information such
+ as a list of defined namespaces.
+
+ Version 0.4 adds per-revision delete flags, log exports,
+ discussion threading data, a per-page redirect flag, and
+ per-namespace capitalization.
+
+ Version 0.5 adds byte count per revision.
+
+ Version 0.6 adds a separate namespace tag, and resolves the
+ redirect target and adds a separate sha1 tag for each revision.
+
+ The canonical URL to the schema document is:
+ http://www.mediawiki.org/xml/export-0.6.xsd
