Does anybody know why the cq:include tag has no addSelector attribute link the sling:include tag has? I'm asking because I'm considering extending the cq:include tag with this functionality. But I'd be interested to know whether there are known issues with this approach before running into them myself...
If I'm not mistaken, CQ inherently adds whatever selectors are on the request, even though you didn't specify something in the tag. If you are trying to only add a selector for one specific include, what is the problem with just using sling:include?
