RH 15 Responsive Design & 508 Compliancy?

Hi all,

We're using a responsive HTML5 output for our help and I noticed there are no accessibility 508 options in the output like there are for WebHelp outputs. I don't see much within the Adobe Community about it unless I've missed something in my search (entirely possible!). Is anyone making responsive HTML5 output 508 compliant? If so, do you have any guidance on how and best practices?

Many thanks for any time & help,

Scottie Gearing
