TYPO3 Core

This is what is in the ext_emconf.php file of that extension:

'constraints' => array(
                'depends' => array(
                        'php' => '4.3.0-',
                        'typo3' => '3.9.9-',
                        'static_info_tables' => '',
                        'cms' => '',
                        'lang' => '',
                ),
                'conflicts' => array(
                        'kb_tv_clipboard' => '-0.1.0',
                        'templavoila_cw' => '-0.1.0',
                        'eu_tradvoila' => '-0.1.0',
                ),
                'suggests' => array(
                        '0' => 'doc_tut_ftb1',
                        '1' => 'rlmp_tvnotes',
                ),
        ),

Now, if the array is wrongly formatted, how should this work? Suggestions are expected to be given like the other constraints...

If the suggestion is given correctly ignoring works, too...

'suggests' => array(
                        'doc_tut_ftb1' => '',
                        'rlmp_tvnotes' => '',
                ),
