Later code requires that `items` be a `List` so this code should either
enforce it here or otherwise sanitise `items` into a `List` at this point
> SPARQL VALUES for ParameterizedSparqlString
> -------------------------------------------
>
> Key: JENA-1578
> URL: https://issues.apache.org/jira/browse/JENA-1578
> Project: Apache Jena
> Issue Type: New Feature
> Components: ARQ
> Affects Versions: Jena 3.8.0
> Reporter: Greg Albiston
> Priority: Minor
>
> ParameterizedSparqlString provides an API for substituting variables within
> SPARQL queries with bound values. It does not support the SPARQL VALUES
> keyword which allows multiple values to be specified. The VALUES syntax
> supports multiple values for a single variable, sets of values for multiple
> variables and multiple sets of values for multiple values.
> Inquiry on 24/07/18 the mailing list about this feature. Patch is forthcoming.
