Attributes @sequence and @kind should not be allowed on p:input in invocation of steps

[raducoravu]

If I have an XProc like this:

    <p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0">
        <p:input port="source">
            <p:document href="document.xml"/>
        </p:input>
        <p:output port="result">
            <p:pipe step="checkReservedWords" port="result"/>
        </p:output>
        
        
        <p:validate-with-schematron phase="classificationValidation" name="checkClassifications">
            <p:input port="schema">
                <p:document href="check-classifications-and-reserved-words.sch"/>
            </p:input>
            <p:input port="parameters" sequence="true" kind="document">
                <p:empty/>
            </p:input>
        </p:validate-with-schematron>
        
        
        <p:validate-with-schematron phase="reservedWordValidation" name="checkReservedWords">
            <p:input port="source">
                <p:pipe step="checkClassifications" port="result" />
            </p:input>
            <p:input port="schema">
                <p:document href="check-classifications-and-reserved-words.sch"/>
            </p:input>
            <p:input port="parameters" sequence="true">
                <p:empty/>
            </p:input>
        </p:validate-with-schematron>
        
    </p:declare-step>

you can create an XProcRuntime object and load the XProc in it without any error reported. But the usages of the @sequence and @kind attributes on the p:input elements should be flagged as errors.
Validating the XProc with the RNG schema flags the problems.
