[humanmarkup-comment] Referents

["Bullard, Claude L (Len)" <clbullar@ingr.com>]

BTW:  earlier in the conference call and in a 
note to Sylvia, I brought up the element type, 
referents, a member of the sign element type. 

Note that since a referent is an instance 
of the concept signified, in most cases, 
it cannot itself be put into the markup. 
It requires a proxy or representation. 

For the example given, a bend in the road, 
one would choose a representation for a 
purpose.  For a real road, a good example 
for a referent proxy is a geolocator.

The value of a referent is likely to be 

<!ELEMENT referent (URI | (some set of element names)+) >
<!ATTRIBUTE referent
   rdf:id  #REQUIRED >

or something like that.  I put the 
URI there because it might be useful to point 
to something uniquely, or to use a unique 
URI as the proxy name.

Ok, Manos.  How much trouble did this start? :-)
