-By default, this mesh draws two separate line strip primitives, each using its own `indices` accessor. The `BENTLEY_primitive_restart` extension specifies that both primitives can be replaced with a single one using a combined `indices` accessor containing primitive restart values.

 ## glTF Schema Updates
 
-The `BENTLEY_primitive_restart` extension is applied to a mesh. Its `primitiveGroups` property is a list of groups of primitives that can be replaced with a single primitive using primitive restart. Each group is described by a list of indices into `mesh.primitives`, along with the index of the accessor that supplies the vertex indices for the replacement primitive.
