Saxon

When using the validation with XSD in Saxon EE, in the case of erroneous attributes only the erroneous attribute is reported in the validation report, but not its associated node in the path. With this path, however, no distinct access via XPath to the erroneous node is possible. As an example for an erroneous path in the error nodes I have created the example below.

<?xml version="1.0" encoding="UTF-8"?>
<PIM>
    <category id="c-1" title="Products"/>
    <category id="c-2" title="Sub-Category"/>
    <category id="c-3" title=""/>
    <category id="c-4" title=""/>
</PIM>

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="PIM">
        <xs:complexType>
            <xs:sequence>
                <xs:choice maxOccurs="unbounded">
                    <xs:element name="category" type="categoryType"/>
                </xs:choice>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:complexType name="categoryType">
        <xs:attribute name="id" type="xs:ID" use="required"/>
        <xs:attribute name="title" use="required">
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:minLength value="1"/>
                </xs:restriction>
            </xs:simpleType>
        </xs:attribute>
    </xs:complexType>
</xs:schema>

<?xml version="1.0" encoding="UTF-8"?>
<validation-report xmlns="http://saxon.sf.net/ns/validation"
                    system-id="file:/example.xml">
   <error line="5"
           column="34"
           path="/Q{}PIM[1]/@title"
           xsd-part="2"
           constraint="cvc-complex-type.3">Value "" contravenes the minLength facet "1" of the type of attribute title</error>
   <error line="6"
           column="34"
           path="/Q{}PIM[1]/@title"
           xsd-part="2"
           constraint="cvc-complex-type.3">Value "" contravenes the minLength facet "1" of the type of attribute title</error>
   <meta-data>
      <validator name="SAXON-EE" version="12.2"/>
      <results errors="2" warnings="0"/>
      <schema file="/example.xsd"
               xsd-version="1.1"/>
      <run at="2023-06-20T06:25:13.022229341Z"/>
   </meta-data>
</validation-report>

For a distinct access to the erroneous node, I would expect the following path:

/Q{}PIM[1]/Q{}category[3]/@title

However, only the following path is provided:

/Q{}PIM[1]/@title
