There isn't a recommended way to handle deeply set lists as per your
example... Or I missed it. I'm not a fan of that plugin.

It is really trivial to do this without any plugins:
https://struts.apache.org/docs/wildcard-mappings.html
Wildcards or using the named-pattern matcher (although in the linked
documentation the heading is "Parameters in namespaces").

It may be possible to use conventions, it might be nice to use annotations
to specify the root and the child actions in the same class for grouping:
http://stackoverflow.com/questions/6037820/is-it-possible-to-use-wildcard-method-invocation-in-struts2-with-conventions-plu

Since you may need to resolve the child entity before fetching the child,
it might be convenient to have them in the same class... save you from
chaining.

Create/Update/Delete using the struts2-rest-plugin are pretty straight
forward but at only one level of access.
