Hello,

A small correction here:

We actually do store a high-level representation of an entity as JS 
object in addition to its XML3D-DOM-object. This has two reasons: First, 
we can store a reference to the XML3D object in the DOM. By this, we can 
directly adapt attributes of an entity instance without having to do a 
DOM lookup by entity ID first. Second, we can also maintain attributes 
that are not represented in the XML3D object, like for example velocity 
(which is used to compute position updates which are then propagated to 
the DOM representation), or in future applications maybe additional 
semantic information to an entity. The actual scene graph representation 
of the XML3D object, however, is not stored as separate JS object, but 
directly copied to the DOM from an external document, which in turn is 
referenced by an attribute of the entity.  The XML3D renderer then 
renders the object solely from its DOM representation.

Best,
Torsten
