Hi All,

I am having some problems with the alt container.  Specifically, how
do we state which alternative (from the group) we choose?

For example, let's say I want to state:

:John :lies "often".

Where often is a literal value that can be one of: "often", "sometimes" or
"rarely".
 
So I tried to write this in RDF using the alt container like this:

<rdf:RDF
  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:e="http://example.org/onto/person#">
  <rdf:Description rdf:about="e:John">
    <e:lies>
    <rdf:alt rdf:ID="degrees">
        <rdf:li>often</rdf:li>
        <rdf:li>sometimes </rdf:li>
        <rdf:li>rarely </rdf:li> 
    </rdf:alt>
    </e:lies>
  </rdf:Description>
</rdf:RDF>

So, while the rdf:alt container gives me my list of alternatives --
I do not see how to choose one of the alternatives.  If I eliminate
the alt container and just choose one ... how do I state it is one
of the enumerated alternatives?

Or is this something we have to do with the RDFS range of 
a property?  

Thanks in advance,

 - Mike
