Hi Sandro,
Sightly blocks/expressions are only aware of the HTML context, not the
whole DOM tree so you cannot use the attributes like this.
However, I assume data-component-id="4" is generally not hardcoded, but
rather coming from some sort of expression, like
data-component-id="${some_expression}". In this case you can pass the same
expression to the Use-Object initialization: @id=${some_expression}
