The attribute has been defined by ETSI here:
https://www.itu.int/rec/dologin.asp?lang=e&id=T-REC-X.520-201210-S!Cor3!PDF-E&type=items

as I wrote, I managed to insert into a schema, but OpenLDAP refuses to create an entry which uses it.
It seems as OpenLDAP sees this as a node such Organization or OrganizationalUnit

I don't want to sound rude but my impression is that this will lead to yet another
attribute with undefined semantics. BTDT.

(Hint: E.g. not every company (legal person) has a EU VAT number.)
