[Corpora-List] Annotation layers: missing reference

[Karen Fort]

Dear members,

I'm looking for a reference on annotations layers.
Can somebody tell me when the "idea" of annotation layers appeared?

I suppose it came from the speech community, but I cannot find a clear 
reference on that.

Thank you for your help!

Regards,
