YAML for Replicator - any documentation on full syntax?

The previous replicator had rich enough documentation. Currently, the ‘new’ replicator has very limited documentation - it seems the only way to figure out the interesting parts (say to load a USD from a path) is to glean it from examples - the palletjack is one.

Any help here? Or is python really the only way to go?

Thx
