Subject   st: How does xtmixed/xtreg deal with missing data?

I using xtmixed for longitudinal modelling of panel data. I know xtmixed
accommodates unbalanced datasets (i.e., some respondents drop out over
time or miss one or more waves of data collection), but what about
missing data within a wave/occasion, e.g., missing information on some,
but not all items within an occasion ? What happens in this instance?
Does all data for this respondent on this occasion get dropped similar
to listwise deletion?

Many thanks to any advice offered,
