Yes, the RMSDK renderer has very poor ePub3 support since Kobo has not updated that renderer in quite a while. For the most part, the RMSDK renderer is being used to allow support for Adobe ADEPT DRM protected ePubs. OTOH, virtually all the ePub3 ebooks using more advanced features display without issue on the Kobo webkit-based renderer.

Later versions of the Kobo renderer were based on the Readium/webkit and Readium 2 SDKs.

DNSB knew the detailed technical background. It seems they were using ACCESS's technology.
