 Vertex attributes are usually stored using `FLOAT` component type. However, this can result in excess precision and increased memory consumption and transmission size, as well as reduced rendering performance.
 
-This extension expands the set of allowed component types for geometry storage to provide a memory/precision tradeoff - depending on the application needs, 16-bit or 8-bit storage can be sufficient.

 Using 16-bit or 8-bit storage typically requires transforming the original floating point values to fit a uniform 3D or 2D grid; the process is commonly known as quantization.
