Non valid turtle from Function

[mnieuwland]

Given the following configuration in the Function tab:

FunctionID	Feature	Value
<Divide>	fno:executes	ex:function
<Divide>	zin:p_dec_a	{omvang}
<Divide>	zin:p_dec_b	36

The following RML file is generated:

<#Divide>
    a rr:TriplesMap;
    a fnml:FunctionTermMap;
    rr:termType rr:IRI;

    fnml:functionValue [
        rml:logicalSource [
            rml:source "source.csv";
            rml:referenceFormulation ql:CSV;
        ];
        rr:predicateObjectMap [
            rr:predicate fno:executes ;
            rr:objectMap rr:constant ex:function
        ];
        rr:predicateObjectMap [
            rr:predicate zin:p_dec_a ;
            rr:objectMap rml:reference [ "omvang" ]
        ];
        rr:predicateObjectMap [
            rr:predicate zin:p_dec_b ;
            rr:objectMap rr:constant [ "36" ]
        ];
    ]
.

I believe this should be:

<#Divide>
    a rr:TriplesMap;
    a fnml:FunctionTermMap;
    rr:termType rr:IRI;

    fnml:functionValue [
        rml:logicalSource [
            rml:source "source.csv";
            rml:referenceFormulation ql:CSV;
        ];
        rr:predicateObjectMap [
            rr:predicate fno:executes ;
            rr:objectMap [ rr:constant ex:function ]
        ];
        rr:predicateObjectMap [
            rr:predicate zin:p_dec_a ;
            rr:objectMap [ rml:reference "omvang" ]
        ];
        rr:predicateObjectMap [
            rr:predicate zin:p_dec_b ;
            rr:objectMap [ rr:constant "36" ]
        ];
    ]
.

Notice the difference in the use of brackets in lines following rr:objectMap (three times, line numbers 13, 17 and 21)
