	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.
