wording issues

Hi all,
In addition to what we discussed today, I just also noticed that the document is interchangeably using "object" and "data type" -- sometimes quite confusingly. Unless someone objects, I'll make a PR changing all occurrences to "data type" which seems to be more frequent.
(As discussed, a "data type" has then individual "properties")
