I approve this PR. However, I do see an issue that I do not how to address with our current metadata. Chem on visual indicates that there is Chemistry present as a visual. It could be made accessible through ChemML, but I do not know how widely it is used. It could also be made accessible with a long description and now that MathML supports Chemistry, that could also make it accessible. So, for now I think we are good, but should I submit an issue about this. There is also the Community Group Chemistry on the Web and in Publishing we could turn to for guidance.
