Querying multiple values from a single key

Question

Bainternet assisted me earler with the relation AND parameter. What I need to do now is determine how to query multiple vales from a single key. If I try to specify two arrays with the same key the query fails. Is there a way to use an array in the value?Something similar to.

'value' => array( 'Install Manual', 'User Manual' ),

I've searched quite a bit with no results. This is where I'm at so far.

$documents = array(
    'post_type' => 'documents',
    'meta_query' => array(
    'relation' => 'AND',
        array(
            'key' => 'document-type',
            'value' => array( 'Install Manual', 'User Manual' ),
        ),
       array(
            'key' => 'document-status',
            'value' => 'current',
        )
    )
);
query_posts( $documents );
get_template_part( 'loop', 'documents' );
wp_reset_query();
