Thread:Extension talk:NamespaceHTML/Mixing html with mediawiki variables

Hi thanks for writing extensions. I've been exploring the SecureHtml extension, but have hit a wall since it's not possible to use mediawiki variables inside the secure html tags. My understanding is that raw html tags allow this possibility (see:https://www.mediawiki.org/wiki/Thread:Project:Support_desk/template_variables_within_html_tags)

Anyways was wondering if your extension can allow this possibilty in the same way. All the best
