Implementation of Selectors Level 4

[kitsonk]

Is it possible to impliment the Selectors Level 4, in particular the parent selector?

The specification for parent selectors can be found here: ​http://www.w3.org/TR/2011/WD-selectors4-20110929/#subject

That would allow for something like:

var parents = query("$[data-dojo-type]");

To return all the immediate parents of any node with the attribute data-dojo-type. Currently there is no way to look "upward" with the query selector syntax.

While dojo/NodeList-traverse adds in the concept of .parent() and .parents() it would be useful to have the concept directly in the selectors.
