Here's what I think I was looking at:

http://www.xapian.org/docs/apidoc/html/classXapian_1_1Document.html#767026a91f3a1421f3d23f7a170509d4

"""
Get data stored in the document.

This is a potentially expensive operation, and shouldn't normally be 
used in a match decider functor. Put data for use by match deciders in a 
value instead.
"""

So values are also poor performance?  I feel like maybe there is a 
terminology confusion here or something, James Aylett mentioned recently 
that a lot of things were renamed, so hopefully we're bumping up against 
that and values really aren't poor performance, for my sake. ;)
