Export as GraphML

Is there a way to export the graph as graphML format?

We want to provide an option to export the diagram as graphML so that the users can use it in other tools like YEd. Currently we are planning to make it in server side. But before spending time on that, just want to know is there any way already (or in future will be) available?

You can certainly do so yourself, but such a feature is not supplied by GoJS.

It appears that the popularity of GraphML has been decreasing
