Schema Validation Error reporting

[Ma...@cataloga.com]

Hi All,

We are using Xerces 1.4.2 and validating our documents against schemas.
When an error is found a very terse message is returned without context.
See example below.

                <xsd:element name="repeatingGroup" minOccurs="1"
maxOccurs="unbounded">
                    <xsd:complexType>
                        <xsd:sequence>
                            <xsd:element name="primaryKey" minOccurs="1"
maxOccurs="1">
                                <xsd:simpleType>
                                    <xsd:restriction base="xsd:string">
                                        <xsd:maxLength value="50"/>
                                    </xsd:restriction>
                                </xsd:simpleType>
                            </xsd:element>
                            <xsd:element name="optionalAttribute"
minOccurs="0" maxOccurs="1">
                                <xsd:simpleType>
                                    <xsd:restriction base="xsd:string">
                                        <xsd:maxLength value="255"/>
                                    </xsd:restriction>
                                </xsd:simpleType>
                            </xsd:element>
                        </xsd:sequence>
                    </xsd:complexType>
                </xsd:element>

	If I leave out primaryKey...
	ERROR Message : The content of element type "repeatingGroup" must
match "(primaryKey,optionalAttribute?)".

I can infer from the error message what is wrong but I do not have context
for where this is, especially in a large document.  

Is any work occurring to improve the error reporting so the user has better
information for correcting the document they wish to validate?

Our current thinking is to keep context from the SAX callbacks and produce
our own error messages but this seems like what should be a feature of the
validator????

Regards,
Martin....
