What counts as a “fixed range” spell for Persistent Spell?

The Persistent Spell feat in Player’s Guide to Faerûn allows a spell to last for 24 hours. The spell to be persisted must have a personal range or fixed range.

I’m having trouble finding a definition of ‘fixed range’ for a spell. One example given, detect magic, has a range of 60 ft. Are only spells with a non-variable range considered fixed?

Is a spell with range touch considered fixed? While the 3.0 Faerûn campaign setting errata specifically excludes touch spells, 3.5 makes no mention of this.
