I'd just like to know why you feel that someone who is both X and Y does not count as being X or Y when something asks if they are whatever it is asking for.
As an example that is used easily in the game, if someone is lawful good then they are both lawful and good. If something effects lawful people then it will effect them, even though they are 'lawful good' and not just 'lawful'.
No, it was very clear. Thank you. I guess I just don't see it that way. If you take a strict literal reading, it says divine spellcaster. Divine is an adjective describing spellcaster. Much like red flower or blue sky. If I say to you that here is a blue flower, why would you infer from that that it might also be yellow, for instance? Divine and Arcane are two very different things, much like blue and yellow, and as such if I wanted to describe a blue flower, I'd call it blue, rather than blue and yellow. I guess I was being 'tongue in cheek' about your comment regarding 'plain english'. Sorry. If you take it as that, divine spellcaster can't mean anything other than a spellcaster only capable of casting divine spells. Completely literal english.
A theurge casts both arcane and divine spells, and as such should not be called a divine spellcaster, since that's not entirely true. He's not only a divine spellcaster, but an arcane one as well. I thought it was stretching it a bit to think that the word 'divine' as an adjective would suddenly imply arcane as well depending on interpretation. By the letter, it doesn't.
To take your example above, lawful and good are two different entities, whereas divine is only one. I don't think you can compare them. If you said divine arcane spellcaster, then the above would be relevant. Again, looking at your balloon example, I'd rule that a yellow popping dart didn't pop a red and yellow balloon, since it's not what the dart does. A red and yellow balloon is very different to a yellow balloon despite the fact that they share some similarities (i.e. both have yellow). To take you above example a bit further, would a 'good' dart affect a creature with 'good and lawful' DR? No, because it requires both, not just one.
Hope that makes sense. Not being brief either!
