It can be used in any RDF-based format whenever you've mentioned
something and want to reference more (typically machine-processable, RDF) 
info about it elsewhere in the Web. 

In non-RDF formats, you could copy the basic idea, just as you could 
copy aspects of RDF's approach to namespace composition and
extensibility. The idea is of course little more than the old-fashioned 
notion of a hyperlink, so no rocket science here.

If you wanted to use it in RSS, you could do it this way:

Starting with a Movable Type RSS 1.0 feed, http://rdfweb.org/index.rdf

<item rdf:about="http://rdfweb.org/mt/foaflog/archives/000043.html">
<title>nearestAirport documentation in Japanese</title>
<link>http://rdfweb.org/mt/foaflog/archives/000043.html</link>
<description>From kota&apos;s weblog, details on using
&apos;nearestAirport&apos; in FOAF files. Thanks kota! The
&apos;contact:nearestAirport&apos; property is a way of

I assume that the semantics of seeAlso are pretty loose - i.e. you can use
it to point to anything, some more RDF, some XML, an HTML page, a PDF file
or whatever?  I.e. in some cases you are getting something
machine-readable, in other cases you aren't.

I have never understood why, in a semantically rich environment like RDF,
one would want to use such semantically fuzzy properties.  Why not use a
more precise property like 'additionalRDF' (a sub-property of seeAlso) if
that is what you mean?
