Thread:Semantic-mediawiki.org:Community portal/How to install the SMW 2.2 ?

SMW 2.3 has a problem with the mw:Extension:NamespaceHTML. I use query. The 'Template:SomeTemplate' transcludes a page 'HTML:SomePage' (from HTML namespace). SMW 2.2 accomplishes this correctly. In SMW 2.3 HTML-namespace flag is lost and the HTML-code is prohibited. How can this be overcome?
