Thanks.  I finally found this same information in the page for the
adjacency_list class template.  However, doesn't this info belong on the
page for the PropertyGraph concept as part of the PropertyGraph
requirements?

Also, I would have found it useful to have a similar interface
(returning a reference to the stored value) for edge and vertex
properties.  In my application I need to associate a rather large amount
of data with each vertex, and it is impractical to copy all of this data
every time you want to access it. I ended up storing a shared_ptr to the
data.
