EPG / Electronic Program Guide XMLT from MediaTailor Channel?

I've successfully created an ad-sponsored FAST channel in Media Tailor. It plays video, inserts ads, runs through Cloudfront and has it's own external domain for delivery. However, in the video industry EPGs or Electronic Program Guide files are almost always included with distributed channels. Has anyone been able to create an XMLT files for EPG generation from Media Tailor channel data and if so, how?

Any assistance or direction appreciated. Thanks.
