Description

After reading https://nakov.com/blog/2009/07/15/jax-rs-path-pathparam-and-optional-parameters/, I tried to define my own:

<resource path="/{uuid}\{version:(/version/[^/]+?)?\}/scan-code/{codez}">
    <param name="uuid" style="template" type="ns:UUID" required="true"/>
    <param name="version" style="template" type="xs:unsignedInt" required="false"/>
    <param name="codez" style="template" required="true" />
    <method id="scanCode" name="PATCH">
        <doc>Scan code</doc>
        <request>
            <!--
            <param name="version" style="matrix" type="xs:unsignedInt">
                <doc>Version of the sales transaction.</doc>
            </param>
            -->
        </request>
        <response>
            <representation mediaType="application/json" element="ns:SalesTransaction"/>
            <representation mediaType="application/xml" element="ns:SalesTransaction"/>
        </response>
    </method>
</resource>

The problem seems to be that the generator treats path params as required.

I was actually trying to define it as a matrix param, but it seems that a matrix param isn't really supported by JAX-RS at the end of the URL, not in middle path segments.
