    There is no need to use the un-parenthesed form - it is a syntactic short form and the full form can always be used. This may make the code generation easier and have less at risk of misalignment.
    ```
    SELECT * {
           VALUES (?x) { (1) (2) (3) }
           }
    ```
    The query formatter does much the same - if it one variable, it uses the short form, but it does not worry about the data being mis aligned:
    
    It is the case of (illegal) `VALUES ?x { (1 2) (3) }` becoming treated as `VALUES ?x { 1 2 3 }`.

> 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.
