ISSUE-41: class membership construct a # c in RIF

http://www.w3.org/2005/rules/wg/track/issues/41

Raised by: Jos de Bruijn
On product: Technical Design

The current specification of BLD [1] defines membership formulas of the form o 
# c. This formula should be read as "object o is a member of class c".
Note that o and c are both terms.

By including this construct in the language, RIF in effect defines a notion of 
classes.

It is unclear whether such a construct is necessary in RIF.  Specifically, it 
seems to conflict with the notion of classes and class membership construct in 
RDF (and OWL).

If there is indeed a need for this construct in the language, this should be 
shown using examples.
