you will need to write them (in XML and in the standalone too).
check if(xml_read_float_array(UV, node, "UV")) {
they write UVs, for Normals do something very similar
instead of the UV attribute, Attribute *attr =
mesh->attributes.add(ATTR_STD_UV, name);
use the normal attribute ATTR_STD_VERTEX_NORMAL
