[BioC] Manual annotation of ExpressionSet object created from scratch

I have an ExpressionSet object that I created from scratch with  
expression data for features identified with Ensembl transcript IDs.  
The ExpressionSet constructor wants a character string for annotation  
data. Is there another way to populate the slot? From an  
AnnotatedDataFrame? Should I write a function that pulls in the data  
with biomaRt?
