keyvalue(context, data)

Render items in a mapping using patterns found in the children of the element.

• header: Rendered at the start, before the first item. If multiple header patterns are provided they are rendered together in the order they were defined.
• footer: Just like the header only renderer at the end, after the last item.

• item: Rendered once for each item in the sequence. Can contain subpatterns key and value.

  If multiple item patterns are provided then the pattern is cycled in the order defined.
• divider: Rendered once between each item in the sequence. Multiple divider patterns are cycled.
• empty: Rendered instead of item and divider patterns when the sequence contains no items.
