$attribute	array	The parameter definition array containing keys like type, heading, param_name, value, etc.
$name	string	The shortcode tag name (element base) that this parameter belongs to.

Usage

<?php
add_filter( 'vc_mapper_attribute', 'my_modify_mapper_attribute', 10, 2 );

function my_modify_mapper_attribute( $attribute, $name ) {
    // Add a custom dependency to all textarea_html params
    if ( 'textarea_html' === $attribute['type'] ) {
        $attribute['description'] = esc_html__( 'Enter your content here.', 'my-theme' );
    }
    return $attribute;
}
