Is it possible to write not interleaved buffers?

[ptc-eparodi]

The BufferBuilder::AddAccessors API seems to rely on data being an interleaved buffer. I was wondering if it is possible to write also non-interleaved buffers with the same API or other APIs?
Something along these lines:

std::vector<float> vertices ={
        -1.0f, 1.0f, 0.0f, // pos0
         1.0f, 1.0f, 0.0f,  // pos1
        -1.0f, -1.0f, 0.0f, // pos2
         1.0f, -1.0f, 0.0f, // pos3
         0.0f, 0.0f, -1.0f, // norm0
         0.0f, 0.0f, -1.0f, // norm1
         0.0f, 0.0f, -1.0f,  // norm2
         0.0f, 0.0f, -1.0f, // norm3
};

const size_t componentSize = sizeof(decltype(vertices)::value_type);     // 4
const size_t stride = 3 * componentSize;                                 // 12
const size_t count = 4;                                                  // ?8

AccessorDesc descs[2] = 
{
          { TYPE_VEC3, COMPONENT_FLOAT, false, { -1.0f, -1.0f, 0.0f }, { 1.0f, 1.0f, 0.0f }, 0 },
          { TYPE_VEC3, COMPONENT_FLOAT, false, { 0.0f, 0.0f, -1.0f },{ 0.0f, 0.0f, -1.0f },  48},
 };

 bufferBuilder.AddBufferView(BufferViewTarget::ARRAY_BUFFER);
 bufferBuilder.AddAccessors(vertices.data(), count, stride, descs, ArrayCount(descs), nullptr);

This code doesn't seem to work. Setting count to 8 is not correct either as then the accessors count is wrong.
Thank you for your help!

Sorry for the slow response. If you are capable, please debug the code and contribute a fix. Thanks!
