What it means
The party identifier's declared scheme (SIREN or SIRET, ICD 6523 codes 0002/0009) doesn't match its length: SIREN must be exactly 9 digits, SIRET exactly 14.
How to fix it
Correct the identifier to match its declared scheme's length, or correct the schemeID attribute to match the identifier actually given.
