In section 17.8, Casting to numeric types, all references to checking
the intermediate value xs:string against the lexical were removed. This
looks incorrect as with the new spec xs:float("foo") would be valid.
For example, for xs:float, the May'03 spec stated:
- If IV is not in the lexical space of xs:float, as defined in XML
Schema Part 2: Datatypes, then an error is raise ("Invalid lexical
value")
- Otherwise, TV is xs:float(IV) ...
But in the Nov'03 spec, it just says:
- If ST is xdt:untypedAtomic, xs:anySimpleType or xs:string or a type
derived fromxs:string, SV is converted to an intermediate value IV of
type xs:string and TV is xs:float(IV).
It seems the rules should follow the form:
- If ST is xdt:untypedAtomic, xs:anySimpleType or xs:string or a type
derived fromxs:string, SV is converted to an intermediate value IV of
type xs:string
- If IV is not in the lexical space of xs:float, as defined in XML
Schema Part 2: Datatypes, then an error is raised ("Invalid lexical
value")
- Otherwise, TV is xs:float(IV)
