- Context: `cbc:EndpointID[@schemeID = '0007'] | cac:PartyIdentification/cbc:ID[@schemeID = '0007'] | cbc:CompanyID[@schemeID = '0007']`
- Test: `string-length(normalize-space()) = 10 and string(number(normalize-space())) != 'NaN' and u:checkSEOrgnr(normalize-space())`

## Why it fails

- A Swedish organisation number (scheme `0007`) is not ten digits, has a hyphen, or fails its Luhn check digit.

## How to fix it

- Write it as ten digits without the hyphen: `5560360793`, not `556036-0793`.
