Exported XML file lacks critical information

Greetings,

When you export 3D models, there is an option to "Save with Meta Data (XML)"

Here is a sample XML saved together with my 3D model:

As you can see, it listed out all the meshes <MeshList> and the seam line pairs <SeamLinePairList> in the model.

The problem is that, the MeshPointIndexes in the SeamLinePairs does not specify which mesh the indexes belong to.
So there is no way to find out which SeamLine belongs to which Mesh, making the data unusable.

Thus I propose the following solution:
For each Mesh in the MeshList, add an attribute called "ID" and assign an unique value to it
For each SeamLine in all the SeamLinePairs, add an attribute called "MeshID" and assgin the ID of the mesh it belongs to.

I have manually added these info to illustrate what the final file should look like. Please see the added info underlined in yellow.

  If you export it as OBJ and inspect the XML you'll see more usable information there. In my view the glb/gltf exporter is not working correctly. And there's more information missing from the XML that would be very usable to have, like tack constraint data.
