Spells, XP loss, and Levels

[gfunk]

Can you cast a spell with an XP cost if it would drop you by one level? I'm playing 3.5 and a rules reference would be greatly appreciated. Thanks!

XP Cost (XP): Some powerful spells entail an experience point cost to you. No spell can restore the XP lost in this manner. You cannot spend so much XP that you lose a level, so you cannot cast the spell unless you have enough XP to spare. However, you may, on gaining enough XP to attain a new level, use those XP for casting a spell rather than keeping them and advancing a level. The XP are treated just like a material component—expended when you cast the spell, whether or not the casting succeeds.

House Rule: I wondered about allowing that, but inflicting a negative level each time it's done.
