Hmisc labels and captions in latex.list()

I am trying to feed a list to latex to use with SWeave, and the list  
comes from contents().  Since it is a list, a caption and label are  
generated by latex.list - these are not overridden by setting the  
parameters (such as caption='myCaption', label='myLabel').

I must clearly be missing something - is there no way to set a caption  
or label with the latex() function when the object is a list?

Thanks.
