## Description
The Abstract Wiki content page has a related Wikidata item id, which can be passed as an argument to the fragment function calls.
The type of this argument is **Wikidata Item Reference/Z6091**, which means that:
* If used directly for a **Wikidata Item/Z6001**, it will fail
* To use it as Wikidata item, one must expand the Wikidata item, and use the page argument in the child "Wikidata item reference" key (as shown below)
{F71814589}
This adds complexity that should be invisible to the user
**Desired behavior/Acceptance criteria**
* [ ] (maybe needed) restrict selection of argument references by expected type
* [ ] When using a function that takes Wikidata item or Wikidata item reference, allow selection of argument reference "wikidata item reference"
* [ ] When selecting "wikidata item reference" for a **Wikidata item/Z6001**, create the correct fetch representation: **Z6821( Z18( Z825K1 ) )**
* [ ] When selecting "wikidata item reference" for a **Wikidata item reference/Z6091**, use argument reference directly: **Z18( Z825K1 ) **
**Devices and Design (URLs or screenshots)**
* Desktop: ...
* Small screens/mobile: ...
