I still don't see where your problem is. What prevents you from 
specifying condition="no_idn"?

If you will call stylesheets with profile.condition=no_idn you will not 
get section marked as condition="idn"

You can assign multiple profiles to single element and you can also 
profile for multiple values:

<phrase condition="idn;registrars">...</phrase>

This sentence will get to the output only if profile.condition will 
contain value "idn", "registrars" or "idn;registrars". It means that 
multiple values in one profiling attribute are treated as disjunction 
(logical *or*). If you need conjuction (logical *and*) then you must use 
separate profiling attributes:

<phrase condition="idn" role="registrars">...</phrase>

During processing you will then use parameters profile.condition=idn and 
profile.role=registrars.

As you can see it is not good to mix unrelated conditions in a single 
profiling attribute. If there is not enough profiling attributes in 
DocBook for you, I will suggest you to add your own attributes to 
DocBook DTD which allow you to precisely markup conditional document. 
You will also need to extend profiling code in stylesheets to handle 
these new attributes.
