it is a bug in the specification of the "helo/nohelo" option.

Obviously you can't have them simultaneously, and a MUST NOT is
straight forward.  A more convoluted specification could be:

| The "helo" property MUST be ignored if the "nohelo" property
| is set simultaneously.

And vice versa in the "nohelo" section.

A strategy "each modifier (or option) defines its own rules"
could result in rare and hard to debug errors.
 
Well, that depends on the quality of individual new options'
specifications.

That affects all modifiers, not only options and exp=.
