epo:hasEUReceivedTenders
        rdf:type     owl:FunctionalProperty ;
        rdfs:domain  epo:SubmissionStatisticalInformation ;
        rdfs:range   xsd:integer .

Why the latter is functional but the former is not?

Consider all props with ranges integer, decimal, date, dateTime, boolean: I think all of them should be declared owl:FunctionalProperty. Eg it won't be any good to have two values for thee flags:

epo:hasEInvoicing  rdfs:domain  epo:ContractTerm ;
        rdfs:range   xsd:boolean .

epo:hasEORoleType  rdfs:range  <skos:Concept> .

epo:hasEOrdering  rdfs:domain  epo:ContractTerm ;
        rdfs:range   xsd:boolean .

epo:hasEPayment  rdfs:domain  epo:ContractTerm ;
        rdfs:range   xsd:boolean .
