Understanding genesis_markup() in Genesis Framework - wordpress

Question

I don't understand how the genesis_markup function turns:
array(
'open' => '<aside class="widget-areainfo-onder-content">',
'context' => 'widget-area-wrap',
'echo' => false,
'params' => array(
'id' => $id,
)
into
"<div class="widget-area">"
I do not understand why the id is not used in the output at all and the aside class is also not used....I would have thought that it should be.....
When I do this in the code:
$before_markup_args = array(
'open' => '<aside class="widget-areainfo-onder-content">',
'context' => 'widget-area-wrap',
'echo' => false,
'params' => array(
'id' => $id,
)
);
d($before_markup_args);
d(genesis_markup( $before_markup_args ));

Answer 1

First, I would like to confirm the missing space:
```
$before_markup_args = array(
'open' => '<aside class="widget-area info-onder-content">',
'context' => 'widget-area-wrap',
'echo' => false,
'params' => array(
'id' => $id,
)
);
```
"Onder" is Dutch for "Below". Thus, "info-onder-content" means "info-below-content". Possibly a title for the widget area.
This is a code example that is used for the genesis_widget_area function, typically found in a functions.php file in a WordPress Genesis child theme.
$widget_area_args = array('before' => genesis_markup($before_markup_args),
);
genesis_widget_area($id, $widget_area_args);
We can understand how this works by looking up the definition of the genesis_widget_area function in the /var/www/html/wp-content/themes/genesis/lib/functions/widgetize.php file.
function genesis_widget_area( $id, $args = array() ) {
if ( ! $id ) {
return false;
}
$defaults = apply_filters(
'genesis_widget_area_defaults',
array(
'before' => genesis_markup(
array(
'open' => '<aside class="widget-area">' . genesis_sidebar_title( $id ),
'context' => 'widget-area-wrap',
'echo' => false,
'params' => array(
'id' => $id,
),
)
),
'after' => genesis_markup(
array(
'close' => '</aside>',
'context' => 'widget-area-wrap',
'echo' => false,
)
),
'default' => '',
'show_inactive' => 0,
'before_sidebar_hook' => 'genesis_before_' . $id . '_widget_area',
'after_sidebar_hook' => 'genesis_after_' . $id . '_widget_area',
),
$id,
$args
);
$args = wp_parse_args( $args, $defaults );
if ( ! $args['show_inactive'] && ! is_active_sidebar( $id ) ) {
return false;
}
