	static void cgltf_write_buffer_view(cgltf_write_context* context, const cgltf_buffer_view* view)
	{
	cgltf_write_line(context, "{");
	cgltf_write_strprop(context, "name", view->name);
	CGLTF_WRITE_IDXPROP("buffer", view->buffer, context->data->buffers);
	cgltf_write_sizeprop(context, "byteLength", view->size, (cgltf_size)-1);
	cgltf_write_sizeprop(context, "byteOffset", view->offset, 0);
	cgltf_write_sizeprop(context, "byteStride", view->stride, 0);
	// NOTE: We skip writing "target" because the spec says its usage can be inferred.
	cgltf_write_extras(context, &view->extras);
	cgltf_write_line(context, "}");
	}

should (according to the spec) write the property target when the bufferview is used for attributes or indices:

When a buffer view is used by vertex indices or attribute accessors it SHOULD specify bufferView.target with a value of element array buffer or array buffer respectively.

This is just an enhancement, not an error :)
