Elements vs Attributes Performance wise

Does anyone have any info on the performance impact of using elements vs.
attributes?

Thanks,

Rob

Attributes have a bit of overhead for name-based lookup. On the other 
hand, that may be faster than linearly searching children by name, if 
that's what you want.

General advice is not to try to microoptimize on this basis. Use elements 
for structure, or for things which must contain structure; use attributes 
for simple-valued annotations that help describe that structure.
