Ah I haven't seen the tests. Seems like this PR might require some more work (see https://rawgit.com/rom1504/docson/fix_first_class_ref/tests/test.html vs https://rawgit.com/lbovet/docson/master/tests/test.html ).

It works in the case I tested, but it seems it breaks in other cases, I'll fix that (and add a test for the case this PR fixes)

[rom1504]

I added a regression test, and remove the type functionnality that was indeed not valid as said in #29

[rom1504]

Ok, I fixed the nested ref test, you can see it works there http://rom1504.github.io/docson/tests/test.html (the gh-pages branch in my work is in sync with the fix_first_class_ref branch)

[rom1504]

That even fixed https://github.com/rom1504/docson/blob/fix_first_class_ref/tests/ref.json#L130

[rom1504]

Not done yet, other members than $ref should be ignored, as said in #29

[rom1504]

Not sure this is valid, it is fairly useless without other properties next to the $ref, and that fix isn't quite clean (it should clone things and all). Closing.
