Example

   //write 3 new docs, returns the docs as well
declareUpdate();
const op = require('/MarkLogic/optic');
const docsDescriptor = [
  {uri:'/optic/update/write4.json', doc:{"desc":"write4"}},
  {uri:'/optic/update/write5.json', doc:{"desc":"write5"}, collections:['write']},
  {uri:'/optic/update/write6.json', doc:{"desc":"write6"}, collections:['write', 'write6'], metadata:{'operation':'write6'}}
];
