You also need to include your module in doc-Service-Telemetry-Framework/assemblies/assembly_advanced-features.adoc

I'm going to get this merged down and imported in to the STF 1.1 documentation updates. If for some reason this misses 16.1.3 we'll need to comment it out downstream, but that's not a huge deal for upstream master docs.

Did a local build and check, and this all loads fine. Merging!
