So I haven't in all my days of being a web designer seen this attribute application of the header link tag:
<link rel="next" href="thecod.html" />
According to this page about RDFa for HTML Authors one could add that piece of code to the header of their HTML document and tell the browser that page as one of a series of related pages.
Is this good for SEO or good for marketing? Who really reads this? In the paragraph in question it doesn't directly mention that the browser reads the value of the href value in link tag but that's what the header is for.
So what's the point of having that in a HTML file header?
