 Currently you can show the children of a particular taxonomy in
 wp_list_categories()

 For these examples in the DB we have the following taxonomy
 {{{
 Books
    Good Books
    Bad Books
 Cars
    Ugly Cars
    Pretty Cars
 Horse
    Brown Horses
    Black Horses
 }}}

 example:
 {{{
 $cats = wp_list_categories('child_of=1');
 }}}

 this will return

 {{{
 $cats = Array(
    [0] 'Good Books'
    [1] 'Bad Books'
 )
 }}}

 Showing a limited number of top level taxonomies is not possible

 example:
 {{{
 $cats = wp_list_categories('number=2&child_of=0');
 }}}

 The expected results is:
 {{{
 $cats = Array(
    [0] Books
    [1] Cars
 )
 }}}

 the actual result is:

 {{{
 $cats = Array(
    [0] Books
 )
 }}}

 I would propose a new argument call '''parent'''

 example:
 {{{
 $cats = wp_list_categories('parent=0&number=2');
 }}}

 which would return:
 {{{
 $cats = Array(
    [0] Books
    [1] Cars
 )
 }}}
