CAL-QUERY definition

[Mark Davidson <markd@xxxxxxxxxxxxxxxxxx>]

Hi,

Section 6.1.1 of cap draft 08

The formal definition has a number of things that are not used in it:
  cauprops
  capcprops
  uprop-list
  cprop-list

There is not a cap-using, so cap-local cannot be defined so should be
removed?

The querycomp and queries seem to be defining a VQUERY which is done in 8.6
and should also be removed.

If I am correct, it should look more like this:

   Formal Definition: The value type is defined by the following
   notation:


         cal-query  = "SELECT"   SP   cap-cols  SP
                      "FROM"     SP   comp-name SP
                      "WHERE"    SP   cap-expr

                    / "SELECT" SP cap-cols SP
                      "FROM"   SP comp-name

         cap-cols    = cap-col / ( cap-cols "," cap-col)
                       / "*"

         cap-col     = ; Any property name found in the component
                       ; named in the comp-name used in the FROM clause.
                       ;
                       ;   SELECT ORGANIZER FROM VEVENT ...

                       ; A component name of an existing component contained
                       ; inside of the comp-name used in the FROM clause.
