There's one tricky bit here: we need to have a <PARENT_SEP> separator if and only if a parent actually contributes connections.

For use on node kind pages, automatically lists edges declared on the current page.

If the parameter "parents" is given a comma-separated list of the parents of the node, inherited edges will also be listed.
