I noticed that the eLife date example includes a a collection date with the pub-type attribute:

            <pub-date pub-type="collection">
                <year>2014</year>
            </pub-date>

That attribute is officially deprecated as of 1.1d1:
http://jats.nlm.nih.gov/archiving/tag-library/1.1d3/attribute/pub-type.html

PMC's recommendation for tagging this date is now by using @publication-format="electronic" and @date-type="collection":
http://www.ncbi.nlm.nih.gov/pmc/pmcdoc/tagging-guidelines/article/tags.html#el-pubdate
(example for v1.0 in the blue box)

I think we should probably stay away from anything that's deprecated.
