		field:
		
		type (required):   dynamic or constant. If you choose dynamic, then the field
		value is read from the row in the ResultSet returned
		from the database. If constant, then each returned row
		from the ResultSet is annotated with the value specified
		in the 'value' attribute.
		
	  name (required):   the name of the attribute that you want returned
		in the product server.
		
		string (optional): whether or not the internal db representation at the local
		site for this field is a STRING, or something else (e.g., a number, etc.). Possible 
		values for this attribute are "true", to indicate that the field is a string, or
		"false", to indicate that it is something else. If this attribute is omitted, a value
		of "false" is assumed, and the attribute will not be quoted in the where clause of
		the underlying SQL statement generated.
		
		dbname (optional): the name of the field within the underlying db. If not
		specified, then assumed to be name
		
		table (optional):  if provided, then the attribute a is selected as
		'table'.'a',and then returned. If omitted, the attribute
		is assumed to come from the default table returned from the
		PS query.
		
		value (optional):  is necessary to provide if type='constant' is selected.
		
		scope (optional):  limits the scope of a field's existence: acceptable values
		are &quot;query&quot;, which signifies that the field is only applicable when
		translating queries: and &quot;return&quot;, which signifies the field is only
		applicable as a return field when converting database results into CDEResults.
