[jira] [Created] (VXQUERY-215) The left operand in the PairConstructor must support ExprSingle

Riyafa Abdul Hameed created VXQUERY-215:
-------------------------------------------

             Summary: The left operand in the PairConstructor must support ExprSingle
                 Key: VXQUERY-215
                 URL: https://issues.apache.org/jira/browse/VXQUERY-215
             Project: VXQuery
          Issue Type: Bug
            Reporter: Riyafa Abdul Hameed


According to JSONiq grammar specification the left operand of the PairConstructor needs to be ExprSingle [1]. Current implementation considers it to be a StringLiteral.

Following needs to be implemented:

*Change the grammar specification of the PairConstructor
*The string should be the result of evaluating the left operand: atomizing it, checking that it results in a single atomic item, and casting it to xs:string. 
*Errors such as jerr:JNTY0004 or err:XPTY0004 may be raised upon failure of one of these steps.
