There are many examples where 'codes' used in attributes are actually English strings
e.g. Organisation Role is a string
Organisation Type is an integer, coded to a string.
Some codes have numeric values, others have string values and there does not seem to be any rational for the distinction. This is clearly causing providers problems: for example
OrganisationRole http://iatistandard.org/codelists/organisation_role has string codes
http://iatistandard.org/codelists/organisation_type has numeric codes
