For now, Selectors can only select elements and a small set of 
pseudo-elements.

In CSS stylesheets, it might, maybe, make sense to select and apply 
properties to "text", as if text runs between tags were wrapped in a 
"virtual element". But I don’t think it makes sense for any other type 
of node. What would it mean to apply properties to comments?

(Selector APIs are another story. There, the semantics could be closer 
to that of XPath.)

I’m not super convinced. It seems that these examples would be used 
between "block-level" siblings, where you rarely have "naked" text 
nodes. (Often, there is at least a <p> element.)

But that’s just my opinion.
