In general, yes, hints rather than full solutions. But sometimes there are really obscure words, such as the Z one in the Christmas alphabetical jigsaw. As a non-German speaker, and not even having a German dictionary, I was completely stuck. True, one could parse it once one had the answer, but I had not managed to do that until I did get it from the forum.
With regard to 6D, I have never heard that expression as an example of 7D. The second word, which is not itself clued, is the only one that will fit when all the crossing letters are filled in. It then seems to be a very subtle way to indicate that the first part is an anagram of Rang Tim, though one could guess that anyway.
