I said "go meta", not " go <meta>". ^_^  I meant a function for generalized
document metadata.

Right, the input part is different, but we can align the output definition.

Let me be clearer, though: there is no way we'd add XQuery to CSS. It's a
redundant query language that browser's are not interested in. Following
its *model* for something is possible, but I think it's far more useful to
align with JS APIs, as authors in general are far more likely to be
familiar with JS stuff.
