<!--
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.
Version 0.7 adds a unique identity constraint for both page and
revision identifiers. See also bug 4220.
Fix type for <ns> from "positiveInteger" to "nonNegativeInteger" to allow 0
Moves <logitem> to its right location.
Add parentid to revision.
Fix type for <id> within <contributor> to "nonNegativeInteger"
