is_taxonomy should return true on taxonomy pages

[thomask]

contrary is_category() and other conditional functions, the is_taxonomy function must have argument $taxonomy, so cannot be used to check if i am on the taxonomy page.

wp-includes/taxnomoy.php should have something like

function is_taxonomy( $taxonomy= NULL ) {
        global $wp_query;
        if (NULL == $taxonomy) return isset($wp_query->is_tax);
	global $wp_taxonomies;
	return isset($wp_taxonomies[$taxonomy]);
}

We already have is_taxonomy().

For something to work in the loop, you may be thinking of is_tax() (which does *not* return true for post_tag and category due to compat reasons -- #11904).

closing as invalid.

is_taxonomy() should be used to check if a taxonomy is registered, is_tax() should be used to tell if its a taxonomy page.
