I would like to have a special "sub-node" that could be attached to other Drupal nodes, that allows authors to include commentary (from the author, so this isn't a comment node) and sample text, to the parent node.
I plan to use the exact same fields for the author commentary and sample text, and to create a view that lists both together. So, it would be OK to use the same node type for both the author commentary and sample text, or at least the same fields. This might also be useful for having an "address" node that could be attached to various nodes and then displayed together on a listing page.
I think the solution would include using node reference fields, but I get tripped up when it comes to theming the parent node form.
My question is similar to this one:
