Is there a way to have a specific custom taxonomy for new 3.1 post formats?
Let's say for example we want to categorize the "gallery" post format with two categories —only available for those kind of posts— as in "portfolio" and "others". How can we do that? Going even further how can we sub-categorize those with a bunch of tags only available for those custom posts (as for example "people", "landscape", "cityscape", etc.)?
Is it better to switch to custom post types + custom taxonomies to do this?
