-   provide a correct "documentation" link to the author guidelines
-   change <issn>1600-0625</issn> to <issn>0906-6705</issn> (see http://www.ncbi.nlm.nih.gov/nlmcatalog/9301549)
-   add a "template" link that points to the CSL style you used to create this one (<link href="http://www.zotero.org/styles/..." rel="template"/>)
 -   change the file name from "Experimental-Dermatology.csl" to "experimental-dermatology.csl"
