Conformance Tests namespaces missing in xpath tests (IIIF)

Hello

I noticed that namespace declarations are missing in IIIF001 and other
XPath related tests in the conformance test suite. In the xacml 2.0
specification examples, namespaces are always present for xpath
expressions in both Policy and context instances. 

E.g., see sample context in ch. 4.2.2:

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

1050 [a174] <ResourceContent>

1051 [a175] <md:record xmlns:md="urn:example:med:schemas:record"

1052 xsi:schemaLocation="urn:example:med:schemas:record

1053 http:www.med.example.com/schemas/record.xsd">

1054 [a176] <md:patient>

1055 [a177] <md:patientDoB>1992-03-21</md:patientDoB>

1056 [a178] <md:patient-number>555555</md:patient-number>

1057 [a179] </md:patient>

1058 [a180] </md:record>

1059 [a181] </ResourceContent>

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

or sample policy in ch. 4.2.4.2

==========

1266 [a269] <?xml version="1.0" encoding="UTF-8"?>

1267 [a270] <Policy

1268 [a271] xmlns="urn:oasis:names:tc:xacml:2.0:policy:schema:os" xmlns:xacml1269

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

1270 [a272] xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

1271 xsi:schemaLocation="urn:oasis:names:tc:xacml:2.0:policy:schema:os

1272 http://docs.oasis-open.org/xacml/access_control-xacml-2.0-policy-schema-os.xsd"

1273 [a273] xmlns:xf="http://www.w3.org/TR/2002/WD-xquery-operators-20020816/#"

1274 [a274] xmlns:md="http:www.med.example.com/schemas/record.xsd"

1275 [a275] PolicyId="urn:oasis:names:tc:xacml:2.0:example:policyid:2"

1276 RuleCombiningAlgId="urn:oasis:names:tc:xacml:1.0:rule-combining-algorithm:deny1277

overrides">

...

1369 [a355] <AttributeSelector

1370 [a356] RequestContextPath="//xacml-context:Resource/xacml1371

context:ResourceContent/md:record/md:parentGuardian/md:parentGuardianId/text()"

1372 [a357] DataType="http://www.w3.org/2001/XMLSchema#string"/>

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

I'm going to add namespaces to IIF001 and other XPath tests in the
conformance test suite. Let me know if you have any objections.

thanks
