In addition to the above pre-defined keywords, conditions can also reference any user defined field as defined in the ItemFields or ItemField properties.
Using equality operators with Boolean keywords is optional, so "Selected" and "Selected EQ 1" are equivalent. The integer and string keywords require the use of the equality or comparison operators. So use "Level > 1" or "Class = 'Group'" instead of just "Level" or "Class".
