WHERE clause optional?

In:
   http://www.w3.org/TR/2005/WD-rdf-sparql-query-20050217/

the syntax indicates the WHERE clause is optional (production [1]), but I 
can't find any indication of what is returned when no WHERE clause is 
provided.  Maybe it's there somewhere; if so, lacking a single 
comprehensive description of the WHERE clause, it is difficult to find it.
