What is the correct name to give to a taxonomy term page template file? I have a taxonomy term page, which is not a view. It just lists all the content for the taxonomy. I would like to customize this page, and I have tried all permutations and combinations of names for the template file. The template file just won't work.
I have tried page--taxonomy--term--5.tpl.php, page_taxonomy_term__5.tpl.php.

What is the right filename to give to the template file, in this case?

I am using Drupal 7.
I use, for instance,

page--taxonomy--term--6.tpl.php

Make sure you clear the cache in Configuration > Performance > Clear all caches after creating your template.
