Dear all,  
I'm currently working with a glazing manufacturer who is providing me with  
glazing properties in .is and .brdf files.  
I've used xml files previously in Radiance to work with BSDF primitives  
and I wondered if some of you have ever come across these extensions and  
knew if they can be converted into a readable format by Radiance.  
Thanks in advance,  
Regards,  
Thibault
