Missing in documentation

[boranin]

In my view, answers to the following would enhance the documentation:

-Why is the dataset schema given in .yaml and the group and organisation schemas as JSONs? Can they all be either?
-What is the create_validators attribute used for? Examples of usage would be of help too.
-field_name - "Existing dataset field names include [...]" - Are these fields defined in the ckan_dataset.yaml file? There are more fields defined in that file than on the [...] list, should they be on the list in the Readme file?
-Can the presets be used for all, datasets, groups and organisation fields or are they specific to datasets only?
-Is the attribute "label" in the "repeating_subfields" key the same as Key label "label" (can have international translations)?
-Is repeating_label in the in the "repeating_subfields" key the same as Key label "label" (can have international translations)?

It might be that all this has been answered somewhere, but I didn't see that even after re-reading the Readme several times.
