I see that I can create subcollections or paths within a database if I create the database then use the "ADD TO" command to add a resource at a specified path. Is this the only way to create hiearchical structure within a database? I couldn't find many details about this in the documentation.

I see that the changelog for BaseX 6.3.1 includes, [ADD] REST: support for hierarchical collections added; details will follow, but I don't see anything about this in the wiki page for the REST module.
