OK, I might be able to get away without that but @snicholas could you confirm this instead?
In the psc base type doc (http://xmlgw.companieshouse.gov.uk/v1-0/schema/PSCBaseTypes-v1-2.xsd) it lists the two options for this field, one of them being NO_INDIVIDUAL_OR_ENTITY_WITH_SIGNFICANT_CONTROL
.
"SIGNFICANT" is spelt incorrectly.
I presume the base type doc is correct and we need to look for the statement with the incorrect spelling?
