JSON-LD 1.0 - multiple values? [SEC=UNCLASSIFIED]

I am having some difficulty navigating the standard with respect to an object having multiple values for the same predicate:

<rdf:Description rdf:about="#myObject">
  <rdfs:seeAlso rdf:resource="#anotherObject1"/>
  <rdfs:seeAlso rdf:resource="#anotherObject2"/>
</rdf:Description>

After looking at the JSON-LD 1.0 Processing Algorithms and API, I have managed to work out that to do mutilple values for a predicate, you put them in an array. It's only if the expanded type of a key has @container that it's not treated as multiple values - it's treated as an RDF Collection.

It would be better if this was stated a bit more clearly in the main document - JSON-LD 1.0. The first mention of arrays in §3.1 "general terminology" gave me the impression that arrays are always rdf collections - it refers you to §6.11 Sets and Lists. I don't see anything up front to the effect that this only applies when there's a @container tag. None of the examples demonstrate this.

It would be good for there to be a section that explains that

{
  "@id": "#myObject",
  "@context": {
    "bar": { @container =  @set }
  },
  "foo": [ {"@id"="a"},{"@id"="b"},{"@id"="c"} ],
  "bar": [ {"@id"="a"},{"@id"="b"},{"@id"="c"} ]
}

means

<rdf:Description rdf:about="#myObject">
  <foo rdf:resource="a"/>
  <foo rdf:resource="b"/>
  <foo rdf:resource="c"/>
  <bar rdf:parseType="Container">
    <rdf:Description rdf:about="a"/>
    <rdf:Description rdf:about="b"/>
    <rdf:Description rdf:about="c"/>
  </bar>
</rdf:Description>
