The thing is that SimpleValue is not the only one that could use 
context. There are dbxrefs with context too. If you made annotation 
objects generally context aware (while it would be left to the 
implementing class to define what to do with the context - much as with 
as_text()), you'd kill all those cases simultaneously.
