Did you see the reply to your original mail I posted recently? I think
it answers at least some of your question.

In short you need to add "vendor-option-space optionSpacedb;" in the
same block as where you use the options. This method requires that the
client asks for option 43 (vendor-specific-options) and knows how to
parse "vendor encapsulation".

If you can't use vendor-specific-options for any reason, you need to
find an option code that isn't in use in the global scope. That would
typically be option codes 224-254 which are for "local use". In that
case you don't need separate option spaces, unless you have clients
that understand the same option codes in different ways. In that case
you should take a look at "site-option-space".
