Filter implementation to be used in combination with {@link FilteringIterator}to return only {@link Literal} values (may be {@link PlainLiteral}s and/or {@link TypedLiteral}s) that confirm to the parsed set of languages.

Parsing null, an empty array is interpreted such that any language is accepted. Parsing "" or null as one element of the array indicated that Literals without any language tag are included. This also includes {@link TypedLiteral}s with the data type xsd:string.

Note that parsing:

an empty array will result in all Literals (regardless of the language) are returned
an array that contains only the null element will result in only Literals without any language tag are returned.
