The entire [XT] manual is your reference of choice, I would say, particularly since you have it in pdf form on your machine. Look at the examples in -help xtreg-, where you won`t see lagged values...

Betreff: st: Panel data and lagged dep variable

Dear Statalist

in a panel test, to what extent is it acceptable a model with no lagged dep variable among the indep variables? Is it always necessary to include a lag dep variable? Moreover: what do you think about a model that has all variables (both y and x) at the same year?
Please: is there a reference that clarify these issues?

Thank you.
