[Exist-open] option exist:serialize with restxq

[Harris, B. T. (GSFC-5870) <ber...@na...>]

declare option exist:serialize "json-ignore-whitespace-text-nodes=yes";

in a restxq application is being ignored.  Is it possible to set this in the response?  What do I need to add to

            <rest:response>
                <output:serialization-parameters>
                    <output:method value="json" />
                </output:serialization-parameters>
                <http:response>
                    <http:header name="Content-Type" value="application/json" />
                </http:response>
            </rest:response>

Thanks.  Bernie
