Re: PROPOSAL: Restrict @prefix declaration to the root element

I think I actually suggested this, but on further thought, it limits some important use cases.

In the structured-data linter, the snippet output is generates with RDFa markup within a div inside the document. Having to declare @prefix definitions in the head is a little problematic, and doesn't keep all the example RDFa in one place; it actually introduces a different copy/paste problem.
