   * [[ch:fields:QID]] mandatory global question ID: could e.g. be a 32-bit (or longer) integer. There could be some attempt to put some meaning into this ID, but it is probably easier simply to assign a random number to it, only ensuring that there are no duplicates.

Here we need to specify just what those answers are, which will not be language-dependent. The enabling answers are determined by the enabled question, not by the enabling question.

+All [[ch:fields:language]]-dependent fields, here marked with "@lang", are held as an array of entries, each one with:
+  * the natural language code;
+  * the field value written in that natural language.
+It is clearly desirable that the languages used in each question should be the same across all fields in that question; though this is not enforced, to allow translation of some fields. This can be checked along with other checks for validity of a question — if the languages are inconsistent, this will throw up a warning.
 ===== Two special cases: place and time =====
 Space / place and time are the two factors that hold a special place of neutrality in science, and they deserve special treatment here.
