Support for lang tags in properties

RDF as well as OSLC and SHACL shapes are clear on the fact that a property declared multiple times with different language tags is counted as 1 property. But as you see reported in, Lyo does not deal well with them if the underlying cardinality is 0…1 or 1…1.

Jim, what do you think about changing the shapes to support this? I.e. changing from a String to string array / set in 4.0 client?
