Re: [incquery-dev] xcore & eiq status

Thanks for checking it. About Eds comment, I repeat myself: "We have said to work amongst the first part; I have tried to look at how EMF does its things, but did not have the time to finish it yet."

I tried to erase all the contents of the plugin.xml and invoke the builder again, and the contents have been written properly. Nevertheless, a full clean usually will result in the absence of the gen_package extension point definition and the query specification extension points. The derived feature extension points are always generated.
