Re: AW: [jwt-dev] JWT2XPDL transformation

[Marc Dutoo <marc.dutoo@xxxxxxxxxxx>]

Hi Miguel

Thanks for this input, I rather agree the "property" element, ex. added 
to the model element NamedElement, would be simple and efficient.

I'll write more about our plans for databinding soon.

Miguel, as we said I'll be glad to welcome you (your colleagues are 
welcome as well) at Open Wide Lyon, so we can speak about what we're 
doing and show it, and about how we may best help each other ! I'll be 
available both weeks 16 and 17 i.e. from the 14th to the 26th of April, 
choose your day - will one day be enough ? I'll put together an order of 
the day in another mail.

Regards,
Marc
