>     add new fields/formats for ls006

please use the style from fields.text which is
machine-readable, the column vertical-bar positions
matter example is Z23-Form 

 270 # 1.6.27 Z23-FORM
 271     |0     |6     |11    |15 |16     |21 |23    |31 |
 278     | PO   |  FRTp|  FRAp    |  FRBp |RMC|   XO |Rc |
 279     | PO   |  FRT |  /// | R | FRB   |RMC|   XO |Rc |
 280     | PO   |  FRTp|  /// | R | FRBp  |RMC|   XO |Rc |


it is obvious that R is 1 bit, and (line 279) bits 11-14 are unused.

don't use markdown table format it is inconsistent with fields.text
and with every other RFC and with the Power ISA itself
