We're using Mosaic with site layouts. Thus we do not need Diazo transforms. Is there some way to switch off Diazo?
At the moment we use an empty transform, copying over all <html> attributes and children into an almost empty theme (just <html><body></body></html> (body is needed, because otherwise plone.protect fails). This works but is a minimal overhead.
thanks for the suggestions. In fact I want the theme to be enabled (I need other features here), just the transform to be disabled. My ideal would be to not have any rules.xml oder theme.html. Thanks for the pointers, I'll dig deeper there.
