Hi Do any one have an example usage of the params-attribute on the nuxeo-page-provider element?

<nuxeo-page-provider auto

                 provider="myProvider"
                 page-size="25">
         params=""

I kind of hoped that one by using the params-attribute could send a value to the NXQL behind the provider in question. That that value is replacing a question mark in the NXQL.
