RE: "If" and "else" in RDF

<- Yes, you can certainly represent the mapping of the production
<- rules in RDF.
<- But, imho, you cannot say "if <class> then <value>" without specifying an
<- agent and a method ... so that untill you do, that construct would always
<- remain vague and useless.

I'm not sure whether <class> and <value> would be the best candidates to go
in such rules (what's the intention of <value>?), but something like "if
<statement> then <statement>" isn't vague at all. Such constructs, like the
rest of RDF and markup in general, only become useful when an agent
(method?) acts upon them...
