            <field-visibility>
                <show id="bpm:workflowDescription"/>
                <show id="packageItems" />
                <show id="bpm:comment" />
                <show id="transitions" />
            </field-visibility>
            <appearance>
                <set id="information" appearance="title" label="Workflow Information" />
                <set id="wfinfo" appearance="" template="/org/alfresco/components/form/2-column-set.ftl" />
                <set id="assignees" appearance="title" label="Assignees" template="/org/alfresco/components/form/3-column-set.ftl" />

                    </control>
                </field>
                <field id="bpm:workflowPriority" label="Priority" set="wfinfo" read-only="true">
                    <control template="controls/workflow/priority.ftl" />
                </field>
                <field id="transitions" set="outcome" />
