Missing AML Examples for Temporal Metadata

[GNREX]

Hi

I have recently been introduced to XMP as a way to tag videos with metadata based on specific times/frames. I believe this ability is called temporal metadata and is described in "Partners Guide to XMP for Dynamic Media" (attached below)
DynamicMediaXMPPartnerGuide.pdf
. I could not find a single example or mention of Parts/Tracks/Ingredients/Pantries in this repo that started a new SDK from Jan 2020. Some examples like "AML_AddTimePartComponent" exist in previous repositories from 2016 from an older version of the SDK.

My question is what was the rationale from removing those examples and what is the best ways to learn about temporal XMP from C++ examples in the new SDK as this is a very powerful feature that seems to be veiled in mystery. Using the old SDK is not a viable solution at the moment.

Thank you for your time
