As a first cut, we want to transcode information based on InstanceIdentifier + DataObject. The implementation needs to use mdsal-binding-dom-codec-api facilities to transcode the DataObject to a NormalizedNode and then turn that into a JSON string.</p> <p>Once we have a prototype we can then evolve it to more effecient transcoding, including stream setup pipelines.</p> <p>Operating System: Windows<br/> Platform: PC</p> MDSAL-39

Provide utility service which will convert Java Generated DTO to JSON
