+    Auto-fill answers with profiles and addresses from customer account.
+
+    There are two types of profiles:
+    1. profiles for answers and 
+    2. profiles for invoice addesses
+
+    Both are handled the same way.
+
+    Each form section/fieldset has its own auto-fill and save to profile 
+    inputs. Each fieldset can define its own profiles by providing the 
+    HTML-attribute data-profiles-id, which defaults to "profiles_json".
+    Currently only the invoice address fieldset uses this to load a 
+    different set of profiles.
+
+    For each section each profile’s answers are matched to inputs inside
+    this section. Only matching ones are shown for auto-fill. If multiple
+    profiles only match the same inputs with the same values (e.g. name)
+    then only the first one is shown as showing multiple profile with the
+    same values is not helpful.
+
+    Feature-Idea:
+    – in the original profile description, strikethrough which answer
+      will be overwritten, followed by the new answer
+    – add new answers with a + in front
+    – change <select> to a list of radio-buttons for multiline-display 
+      of profiles?
