> I'm opening this bug report for Xerces JIRA records and tracking.
> Here's an example which illustrates the problems highlighted in this bug report. With this bug report, we are targeting improvements on current code-base on SVN.
> XML document:
> <List>2 4 6</List>
> XML Schema 1.1 document:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
>
> <xs:element name="List">
> <xs:complexType>
> <xs:simpleContent>
> <xs:extension base="INTLIST">
> <xs:assert test="data($value) instance of xs:integer+" />
> <xs:assert test="count(data($value)) = 3" />
> </xs:extension>
> </xs:simpleContent>
> </xs:complexType>
> </xs:element>
>
> <xs:simpleType name="INTLIST">
> <xs:list itemType="xs:integer" />
> </xs:simpleType>
> </xs:schema>
> The schema above must successfully validate (i.e the schema assertions specified in the above example, must evaluate to true. The XPath 2.0 function "data" gives us the 'typed value -- of XDM type xs:anyAtomicType*' of the argument.) the XML document specified above.
> Per the relevant sections of the spec here, http://www.w3.org/TR/xmlschema11-1/#sec-cvc-assertion, the point 2 at this link says:
> <quote>
> For complex types with simple content, the element node may be referred to as ".", while its content may be referred to as "$value". Since the element node, as a consequence of clause 1.2, will normally have the type annotation anyType, its atomized value will be a single atomic value of type untypedAtomic. By contrast, $value will be a sequence of one or more atomic values, whose types are the most specific (narrowest) built-in types available.
> </quote>
> Presently (for the current code-base on Xerces SVN), for complexType with simple contents, $value doesn't have a typed value of kind xs:anyAtomicType*. With the current code-base on Xerces SVN, $value as per examples cited in this bug report, is just a string "2 4 6". I believe, this is a bug as per the XML Schema 1.1 spec.
> I'll try to solve this bug ASAP.
