Item I would like to see in the next version

Some sort of group or selection set tag. I am working with Modo and Houdini and it would be nice if there were some kinda of schema element that preserved the selection sets I defined in Modo in the Collada format.

Hi,

Could this be done using the ‘layer’ notion already in COLLADA ?
I have seen this used in Maya for example to group objects. One object can be in several layers


<xs:attribute name="layer" type="ListOfNames">
  <xs:annotation>
   <xs:documentation>
 The layer attribute indicates the names of the layers to which this node belongs.  For example, a value of “foreground glowing” indicates that this node belongs to both the ‘foreground’ layer and the ‘glowing’ layer.  The default value is empty, indicating that the node doesn’t belong to any layer.  Optional attribute.
