I will be using an SMIL file to schedule videos in the Wowza Streaming Engine and create an HLS file for them. To add SCTE-35 markup, there are two ways to add them.

- Insert EXT-X-SCTE35 tags in the HLS file
- Insert SCTE35-CMD, SCTE35-OUT, SCTE35-IN attributes in the EXT-X-DATERANGE tag

How do I do that using WSE? Documentation only for ID3 tags(how-to-enable-player-side-ad-insertion-using-wowza-streaming-engine) is present currently.
