What are these undocumented arguments for register_taxonomy?

Question

The Wordpress codex has an example of the register_taxonomy() function at http://codex.wordpress.org/Taxonomies that shows arguments that are not documented in http://codex.wordpress.org/Function_Reference/register_taxonomy.

In particular args['sort'] and args['args'][order_by].

What's the story with these?

Answer 1

I suspect the Taxonomies Codex entry is simply out of date.

Per source, there are no 'sort' or 'orderby' args for register_taxonomy().

Given the purpose of the register_taxonomy() function, it doesn't even really make sense for this function to include sort/orderby parameters. Such parameters would be relevant to listing taxonomy terms, not to registering the taxonomy itself.
