Optional field about typesystem HOT 2 CLOSED

So, fields are required unless they have a default value set. (Eg. Similar to arguments on a Python function)

Using default=None or default=“” would make the field optional, and indicate what value should be used when it is missing. (Also, allow_blank and allow_null will set a corresponding default, too)

So, typesystem doesn't really support true optional fields. This is a problem with the data I'm working with (Google Music). There are plenty of fields that may simply not exist in the data. For many, it either doesn't make sense to default the values or might actually cause calls to fail. Some of these include YouTube video references, album art links, attributions, rating, last rating timestamp, and more. Every other schema library I've used before supported true optional fields. This is a deal-breaker as far as my current use case and at least one potential use case is concerned.
