I have to agree; hpd describes this entire group as "actionpoints" and 
lists:

- breakpoints
- watchpoints
- barrier

and we've suggestions for additions such as:

- catch syscall
- catch dlopen (?)
- catch signal
- catch fork
- catch clone
- catch exec

for all of these they have several things:

- the commands to run when the event is triggered
- should the hit be verbose or silent
- should the end result be to stop or continue (attribute or not?)
- ?

that can be characterised as attributes; as, dare I suggest, you're 
reading into the intent of the HPD, the way to do this is would be with  
-silent option to the commands that create and edit (see actions) 
actionpoints.
