COV:compenso does not reference currency in rdfs:range

[ioggstream]

When

• an entity reference a currency amount

I expect

• to reference both the currency and the valute

Instead

• COV:compenso rdfs:range xsd:double, so it cannot map currency changes (e.g., ITL/EUR,... for salaries before 2002)
