Hi,

The XML Schema Validator
(http://www.w3.org/2001/03/webdata/xsv)
consistently crashes (see bug report copy/pasted below) when
submitting a local (i.e. non-web-based) schema with all 3 options (show
warnings, keep going, complete schema) selected.

Basically, I updated this part of a 400-lines schema that validates correctly:

<xs:simpleType name="lb" />

<xs:complexType name="pb">
   <xs:attribute name="n" type="xs:positiveInteger" use="required "/>
   <xs:attribute name="column" use="required">
               <xs:simpleType>
               <xs:restriction base="xs:string">
                       <xs:enumeration value="a"/>
                       <xs:enumeration value="b"/>
               </xs:restriction>
               </xs:simpleType>
   </xs:attribute>
</xs:complexType>

to this version that leads to the crash:

<xs:simpleType name="merge-split-word">
       <xs:restriction base="xs:string">
               <xs:enumeration value="keep-dash" />
               <xs:enumeration value="discard-dash" />
               <xs:enumeration value="no" />
       </xs:restriction>
</xs:simpleType>

<xs:complexType name="lb">
   <xs:attribute name="merge-split-word" type="merge-split-word" />
</xs:complexType>

<xs:complexType name="pb">
   <xs:attribute name="n" type="xs:positiveInteger" use="required "/>
   <xs:attribute name="column" use="required">
               <xs:simpleType>
               <xs:restriction base="xs:string">
                       <xs:enumeration value="a"/>
                       <xs:enumeration value="b"/>
               </xs:restriction>
               </xs:simpleType>
   </xs:attribute>
   <xs:attribute name="merge-split-word" type="merge-split-word" />
</xs:complexType>


Moreover, to obtain the bug report below, I had to select the "xml,
but labelled text/plain" option, as none of the 3 others would display
correctly the bug report (there was a short error message, but no
explanation or bug report).

Best regards,
