The following very useful article
 A Study of Innovative Features in Scholarly Open Access Journals
by Bo-Christer Björk in J Med Internet Res 2011;13(4):e115
URL: http://www.jmir.org/2011/4/e115/
doi: 10.2196/jmir.1802 <http://dx.doi.org/10.2196/jmir.1802>
PMID: 22173122<http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=22173122>

carries the following text
This is an open-access article distributed under the terms of the Creative
Commons Attribution License (http://creativecommons.org/licenses/by/2.0/),
which permits unrestricted use, distribution, and reproduction in any

The strange thing is that if you want to download a PDF copy of the article
you can only do so after payment of $22 !
i can only see this as a restriction and one which makes re-use a bit more
difficult.
In previous discussions on this list we already saw that CC-BY license in
principle does not forbid anyone to sell an article. However I don't think
that this has been the intention when the CC-BY licensing was developed.
Perhaps CC-BY-SA is a more restricted license but in this combination it
does not allow selling the article or a processed form (for example
PDF)......This would be a restriction that I can live with
