That would require an addition to the Selectors spec and that comes too late in the process of that spec. I would recommend changing the Selectors API on document.querySelector and document.querySelectorAll to allow a second argument being a node or null. If it's a node, then the results simulate your :scope > SELEC above, the scope being that node and SEL being the selector passed as the 1st argument. If it's null, well, it does what it does today. </Daniel> -- Co-Chair, W3C CSS WG
