Thank you for preparing this!

I've left a couple of suggestions to make it clearer - but I believe it already includes all the neccessary parts, we just need to improve them a bit.

I cannot provide you with the PostgreSQL schema, we will need someone from the backend team for that.

Looks good overall, just a couple of comments to improve this.

Please remember to create a PR to the user doc, mentioning this attribute (just a mention is ok, we did the same for date and time: https://doc.ibexa.co/projects/userguide/en/latest/pim/work_with_product_attributes/ )

Also, please have a look at the read the docs error - I think we (I) have lost the mkdocs.yml modification during conflict resolution, could you please readd the symbolattribute_criterion.md file to make the build pass?

Another thing which I forgot about: please add the new LTS update to the table of LTS updates (https://github.com/ibexa/documentation-developer/blob/4.6/docs/ibexa_products/editions.md#lts-updates)
