Thanks for your comments on the Primer!

The simplest way to fix this was to change the above to "an attribute 
introduced by RDFa," which is what I did.

I've added a bit of an explanation before the first @about.

I'd rather not change the document structure at this point. I'm hoping 
that I don't have to explain relative URLs to HTML authors :)

Maybe you were reading a previous version? The diagram in Section 2.1 
talks about a "web page as a node," and Section 3 also mentions nodes.

I think this is the idea of a relative URL, which should be clear for 
most HTML authors. Hopefully, the small tweak I made above from your 
earlier comment will further help this.

Thanks again!
