(I suppose it is implicitly constrained by what the individual renderers recognise.) The nearest to a registry I can find is at https://docs.microsoft.com/en-us/typography/opentype/spec/ttoreg, but that appears to be limited to what Microsoft supports - "The tag registry defines the OpenType Layout tags that Microsoft supports". None of the Indic 3 script tags are there. Richard.
