Add stockNumber #1670

Resolves: #1670

Please have a look.
I introduced stockNumber.

I was not sure if I should model this as an array of Objects to state the sources of the stockNumber too. Or just like this.

LGTM, thanks!

We're fine with either solution.

There might be use cases where $$q (Qualifying information) could be relevant, but we don't need it yet.

Issue is missing, I don't know the context. You modelled this field at root level. Is this OK? What is the difference to callnumber (which is modelled under the item subtree)?

Thx for the reference. Have you considered to put this field under publication?
