Validator fails on xslt compiled by schxslt 1.9.x and saxon-he 11.3

[rkottmann]

Hi,

I am developing a new validator configuration at https://projekte.kosit.org/eforms/validator-configuration-eforms

There, I use schxslt and Saxon-He in newest versions (see pom.xml). When I try to run the validator with the compiled XSLT using the following ant snippet (see build.xml):

 <java jar="${lib.dir}/${validator.artifact.name}" failonerror="true" fork="true" dir="${build.dir}">
            <arg value="-l" />
            <arg value="debug" />
            <arg value="-s" />
            <arg value="scenarios.xml" />
            <arg value="-r" />
            <arg value="${build.dir}" />
            <!--<arg value="-\-html" />-->
            <arg value="-o" />
            <arg value="${reports.dir}/eforms-sdk-examples" />
            <arg value="${eforms-sdk.instances.dir}" />
        </java>

I get the following Error:

May a newer Saxon He Version help?

well, if the compiled schematron contains higher-order-functions this won't work with the included Saxon HE and I don't think upgrading would solve this.

If schxslt generates this kind of xsl instruction which is not supported by saxon HE, I would consider this as a bug or at least optimization potential of schxslt.

[rkottmann]

Upgrading works. I am not into all changelogs of Saxon, but it has to do with XSLT3 etc. support and might work with versions > 10.

However it surely works with 11.3.

I tested it with this snippet:

<target name="eforms-sdk-examples-validated-with-schxslt" depends="compile-test">
        
        <xslt in="${eforms-sdk.instances.dir}/CEI.xml" style="${eforms-sdk.schematron.validator}" destdir="${reports.dir}" out="${reports.dir}/cei.svrl">
            <classpath  >
                <pathelement location="${lib.dir}/${saxon-he.artifact.name}"/>
                <pathelement location="${lib.dir}/xmlresolver-4.2.0.jar"/>
            </classpath>
            <factory name="net.sf.saxon.TransformerFactoryImpl" />
<!--            <fileset dir="${eforms-sdk.instances.dir}"/>-->
        </xslt>
        
    </target>

which I just pushed to https://projekte.kosit.org/eforms/validator-configuration-eforms

In any case, I suggest to upgrade all pom dependencies or at least Saxon to newest versions. It is also advisable to switch to schxslt based Schematron validation, because the ISO based one is officially deprecated in favor of schxslt.

In my special case, I need it urgently, cause I have to deliver the validator-configuration-eforms by mid of July.

The validator uses the Saxon HE version 9.9.1-7, the latest production version is 11.4 - this is a major difference....

We will upgrade to a recent saxon version with the next release targeted for december

upgraded to 11.4 in main
