SMS 2dm format NS cards

I recently was looking at some .2DM output that wasn't working with an old script and I was wondering whether the format has changed. The cards in question are like:

NS  13479 -13205 28NS  13726 14041 14374 14754 15169 14753 14373 14039 -14040 29NS  13750 14062 14392 14063 14064 14065 14066 14067 14068 14069NS  14393 14777 15199 15622 16018 16017 15621 15198 14776 14391NS  -14061 30NS  14032 14033 14034 14035 14369 14750 15165 14751 14371 14372NS  14752 15166 15593 15991 15988 15590 15589 15161 14749 -14368 31NS  14321 14700 15103 15529 15925 16291 16613 16290 15924 15528NS  15102 -14699 32NS  15147 15148 15149 15574 15966 15967 15968 15969 16326 16633NS  16894 17130 16893 16632 16325 15965 -15573 33NS  15184 15185 15611 -15186 34NS  15577 15578 15579 15972 -15971 35NS  15982 15983 15984 16342 16649 16911 16647 16339 16341 -16340 36NS  16351 16359 16360 16659 16658 16354 -16352 37

.... which appear to have an identifier after the final, negative node.

This doesn't seem to match the documentation at http://www.xmswiki.com/xms/SMS:2D_Mesh_Files_*.2dm#Nodestrings

Is the final number a nodeString entity ID?

Also, the wiki page says the 'BCS' card is obsolete, but it is included in http://www.xmswiki.com/xms/SMS:2D_Mesh_Files_*.2dm#Sample_File_2.

Perhaps the http://www.xmswiki.com/xms/SMS:2D_Mesh_Files_*.2dm#Changes_from_10.1_to_11.0 section should say:

* BC 0, BC 1, and BC 1, replace BCN, BCS and BCE

Is there better documentation somewhere else?

In version SMS 11.1 the ns card now includes a nodestring id value after the negative value (see link below)

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.
