Perhaps they should be added to the internals manual.  The pattern would 
seem to be to take '16.5 Output Templates and Operand Substitution' and 
add two subsections, one for generic 'Operand Modifiers' and another for 
machine specific 'Machine Operand Modifiers'.

Then someone would have to look in all the target PRINT_OPERAND 
implementations and document the state of the art.  That could be a bit 
of work.
