[R] Novice lme split plot model specification

I am a little confused about a simple model specification in lme().
I have Treatments A (levels=1:2) and B (levels=1:2), Blocks (1:10), 
response Y. Levels of treatment A  are assigned at random to entire blocks, 
and all levels of B are applied to plots within each block.

(I believe that if all levels of A were applied to each block, then the 
correct model statement would be:
model <- lme(Y ~ A*B, random = ~1|Blocks).)

How would I specify the statement for my situation?
Thanks for the help.
