Subject: conformance tests, datatype in attribute value elements of Request.xml files to be removed

Hello,


Summary: I think that I'm going to remove DataType attributes in Request.xml files from
conformance tests. They pass schema validation, because schema allows
them. However, they can potentially create confusion if the data types
do not match between Attribute and its children AttributeValue elements.


Also, the spec document defines that types should be in the parent Attribute element.


Explanation:


in some conformance tests, we have datatype attribute in AttributeValue
elemnts. The xacml 2.0 schema doesn't specify exactly what should be in
AttributeValue elements:

========

    <xs:complexType name="AttributeValueType" mixed="true">

        <xs:sequence>

            <xs:any
namespace="##any" processContents="lax" minOccurs="0"
maxOccurs="unbounded"/>

        </xs:sequence>

        <xs:anyAttribute namespace="##any" processContents="lax"/>

    </xs:complexType>

========


However, the current spec document has this in chapter 6.8:

=============

3043 The data-type of the <xacml-context:AttributeValue> SHALL be specified by using the

3044 DataType attribute of the parent <Attribute> element.

=============


Here's an example conformance test, look at the duration attribute values:


========== IIC154Request.xml

<?xml version="1.0" encoding="UTF-8"?>

<Request

      xmlns="urn:oasis:names:tc:xacml:2.0:context:schema:os"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xsi:schemaLocation="urn:oasis:names:tc:xacml:2.0:context:schema:os

        urn:oasis:names:tc:xacml:2.0:context:schema:os.xsd">

    <Subject>

        <Attribute

             
AttributeId="urn:oasis:names:tc:xacml:1.0:subject:subject-id"

             
DataType="http://www.w3.org/2001/XMLSchema#string">

            <AttributeValue>Julius Hibbert</AttributeValue>

        </Attribute>

        <Attribute

             
AttributeId="urn:oasis:names:tc:xacml:1.0:conformance-test:test-attr"

             
DataType="http://www.w3.org/TR/2002/WD-xquery-operators-20020816#yearMonthDuration">

            <AttributeValue

                 
DataType="http://www.w3.org/TR/2002/WD-xquery-operators-20020816#yearMonthDuration">-P5Y3M</AttributeValue>


        </Attribute>

    </Subject>

    <Resource>

        <Attribute

             
AttributeId="urn:oasis:names:tc:xacml:1.0:resource:resource-id"

             
DataType="http://www.w3.org/2001/XMLSchema#anyURI">

           
<AttributeValue>http://medico.com/record/patient/BartSimpson</AttributeValue>

        </Attribute>

    </Resource>

    <Action>

        <Attribute

             
AttributeId="urn:oasis:names:tc:xacml:1.0:action:action-id"

             
DataType="http://www.w3.org/2001/XMLSchema#string">

            <AttributeValue>read</AttributeValue>

        </Attribute>

    </Action>

</Request>

==========



thanks,

Argyn
