I was going to ask this in the Simple Q&A, but I don't think it is that simple. It looks to me as if a spellcasting class is one with a spell-list and defined spells per day. A class that improves or advances another class is not a spellcasting class.
Thus wizard is a spellcasting class, but Loremaster is not. Ur-Priest is a spellcasting class, but Mystic Theurge is not. For if Mystic Theurge were a spellcasting class, then one could advance it with a level of Loremaster.
When a new loremaster level is gained, the character gains new spells per day (and spells known, if applicable) as if she had also gained a level in a spellcasting class she belonged to before she added the prestige class. She does not, however, gain any other benefit a character of that class would have gained. This essentially means that she adds the level of loremaster to the level of some other spellcasting class the character has, then determines spells per day, spells known, and caster level accordingly.
In other words, a wiz3/clr3/MT1 could take a level of Loremaster, choose MT as the class advanced, and thereby advance both his wizard and cleric levels in addition to getting more skill ranks and a Loremaster secret.
Maybe that doesn't seem ridiculous. But consider if, for the sake of argument, one were to consider a class like Mystic Theurge to be a spellcasting class, and then ask whether it is arcane or divine. Is it both or neither? Suppose it depends on the kind of spellcasting advanced. Then if Mystic Theurge were a spellcasting class because it advanced spellcasting, it would have to be both arcane and divine, since it advances both arcane and divine spellcasting. Then in a build where Loremaster advances MT, the Loremaster class would also be both arcane and divine, since Loremaster would inherit its type(s) from the spellcasting class it advances, which in this case is MT. But if Loremaster were both arcane and divine it could be advanced by either half of MT- divine spellcasting, say. A loop would result that would greatly increase the level of wizard spellcasting, since wizard spellcasting increases by +1 every cycle. This is surely ridiculous. And thus neither Loremaster nor Mystic Theurge would be spellcasting classes.
If Mystic Theurge is not a spellcasting class, then the caster level of an Ur-Priest is very low. A wiz10/UP2/MT 8 has a caster level of only 7.
To determine the caster level of an ur-priest, add the character’s ur-priest levels to one-half of his levels in other spellcasting classes. (Any levels gained in the cleric class by an ex-cleric don’t count.)
The spells per day and spells known would be as a wiz18/UP10, but the rules for Ur-Priest look strictly at class levels, and wouldn't count MT levels at all. 2 Ur-Priest levels plus half the wizard levels is only 7. I am not sure of this, or I would reply to Q1617 of the Simple Q&A thread.
TL;DR: If Loremaster and Mystic Theurge were spellcasting classes they could, by their wording, advance each other. But if they are not, then Ur-Priest does not work well with these classes.
