Great!

To flesh out matters a little more with regards to <link/> or "Link:" 
and @rel:

1. the relationship between an HTML document (conventional i.e., not 
embedded data islands via RDFa, Microformats, or Microdata) in the 
loosest form is via "related" as opposed to "alternate" -- typically, 
you would be expressing the triple: <HTMLDocURL> xhv:related 
<SomeLinkedDataEntityName> ;

2. if an IANA predicate doesn't work then simply use the Linked Data URI 
of a predicate that best reflects the relationship between the HTML 
document and the entity denoted by a Linked Data URI -- e.g., <link 
rel="http://www.w3.org/2000/01/rdf-schema#seeAlso" 
href={SomeLinkedDataEntityName} .../>
