Mukul Gandhi commented on XERCESJ-1559:
---------------------------------------
The following schema example I posted,
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:complexType name="T1">
<xs:sequence>
<xs:element name="a"/>
</xs:sequence>
<xs:assert test="not(a/*)">
<xs:annotation>
<xs:documentation>no child elements within 'a' are
allowed</xs:documentation>
</xs:annotation>
</xs:assert>
</xs:complexType>
</xs:schema>
doesn't declare an element, but an XML instance element is validated via the
xsi:type reference in the instance document. I'm still not clear, where the
issue is.
Thanks,
Mukul

> Components: XML Schema 1.0 Datatypes, XML Schema 1.1 Datatypes
> Affects Versions: 2.11.0
> Reporter: Jorge L. Williams
> Assignee: Mukul Gandhi
>
> In the latest XSD 1.1 branch, it looks like simple type assertions are not

> attaching a schema and instance documents as a reference.
> If I do
> java -cp $CLASSPATH jaxp.SourceValidator -fx -xsd11 -a assertion.xsd -i
> even_bad.xml
> I get a correct error, but if I do
> java -cp $CLASSPATH jaxp.SourceValidator -fx -xsd11 -a assertion.xsd -i
> number_bad.xml
> I don't get an error at all.
