One mechanism I've considered is to create a jQuery library that implements designed-in profiles through DOM re-writing. This way, I can remove dependencies on externally loading a profile I'm aware of, as an author, and it also allows me to address other issues of 1.0 vs. 1.1. It isn't a generalizable solution, but as an App writer, where I know the profiles I depend on, and have some control over the HTML markup, it seems like a reasonable solution.

I'm not aware of any JavaScript RDFa parsers that are up-to-date with RDFa 1.1 LC. That being the case, I'd end up re-writing CURIES and Terms in RDFa properties as necessary to be 1.0 compliant, but I'd rather not have to do that.
