Extract XMP metadata from specific Photoshop Layer in After Effects

How do it extract XMP metadata from specific Photoshop Layer in After Effects?

I am just getting my hands dirty with metadata.

I know it is possible to attack metadata to a layer/layerset in Photoshop, but how to I get it out in After Effects.

Here is the process.

I create BunchaLayers.psd.

Using the PerLayerMetaData.jsx file attached.

I use the setCommMetadata("something") function to attacked metadata to a selected layer.

I know that is is there because I check it using the exportLayerMetadata().

I save and imprt BunchaLayers.psd into AE as a comp.

Here I am lost.

I select my layer in the project window and check the XMP metadata window.

I can't find my comment.

Is the XMP data actually attached to the layer I imported in AE?

I want to be able to select the layer and see that the data is attached.  Is this possible?

If it is will it work on layersets (comps in AE)?

I would appreciate any layer specific XMP insight.

Thanks for looking.
