Hi Enrico, all
I like your sugestions but think we shouldn't use any special characters cause they can be really tedious to handle for a programmer.

> If we use the separator char '&': ...

I guess a third possibility to provide for multi-modality would be to allow for multiple modes in a modalitiy, as e.g.
<modality set="basic_modalities">
 <mode="face"/>
 <mode="voice"/>
</modality>  

Regards,
felix

>             - voice
>             - body

> mode="face">  </emotion>

>      <modality id="m2" set="basic_modalities" mode="voice"/>

> A more compact representation could be obtained by

> A similar solution has been proposed by Bjoern for Core 1,

> 
> <emotion>
>      <category set="everyday" name="excited"/>
>      <modality set="basic_modalities" name="face&voice"/> </emotion>
> 
> Or, if multiple modality sets are allowed for the same annotation:
> 
> <emotion>
>      <category set="everyday" name="excited"/>
>      <modality set="basic_modalities&my_modalities" 
> name="voice&music"/> </emotion>
