> 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.
