MULTIPLE fields not implemented

[graybeal]

The Language field in Data File Language is supposed to be cardinality MULTIPLE but it isn't. (It is the second field, the first one being Primary Language.)

To see this, try filling it out. When I try filling it out I have no controls for a MULTIPLE field. Data File Descriptive Attribute also doesn't fill out with MULTIPLE controls.

The only significant difference I can see between the GDMT template that works, and this one that doesn't, is that the minItems setting is 0 in this one, but is 1 in GDMT.

And if I take Data File Language element and put it in a template and try filling out that template in Chrome, it looks like this image. (It fixes itself as you fill it out, but the default visualization is wrong.) So something isn't right with that element.

I tried one more test, creating the element manually from the fields. This worked perfectly (where "worked" means when I filled it out.) But here's a key bit: When you turn on MULTIPLE option for a field, the default minItems is 1, not 0. So that's why the minItems in the working one is 1, and probably the software was never tested when the value is 0. (I'm not saying the code is 'right', just saying that's what the code expects.)

[graybeal]

So, set minItems to 1 by default for the multiple fields. This is a mildly weird workaround, but I don't think the default will ever be set to 0. If it is we'll have to fix the workaround, but there's no way to set a minimum in the spreadsheet at the moment.

Just so I don't forget... I think this is a missing schema:identifier on the items object
