Custom Template for Specific Taxonomy

It was told that to use a different template for an specific taxonomy, I could create, for example, a file called: “page-taxonomy.php”.

I am using Twenty Ten theme, and I created a taxonomy called Services, It is appearing, but it is getting the template from loop-single.php, and not even from loop-page.php, because “Services” is a taxonomy of the type Page.

I tried adding:

<?php
/*
Template Name: Services
*/
?>


So I could be able to choose from the UI, and yet this not appear at the Add Page section.

Can anyone help me?
