Show which element(s) are involved at each error point: - When an element is missing the "key" attribute, show the element - When an element is not an attribute set, show the element - When comparing keys fails, show both elements being compared - When calling operator fails, show which element was being processed This provides concrete context using ValuePrinter with errorPrintOptions. Note: errorPrintOptions uses maxDepth=10 by default, which may print quite deeply nested structures in error messages. This could potentially be overwhelming, but follows the existing default for error contexts.
