Thanks. I see "Nodestrings now contain an id. For more information, see 2D Mesh Nodestrings Menu." there but I don't see any documentation on the new NS card. Also, the only nodestring example in the 2DM card documentation at http://www.xmswiki.com/xms/SMS:2D_Mesh_Files#Sample_File_2 uses the obsolete and undocumented cards.
