Last week we agreed that disallowing text number patterns that contained a # symbol and either a P or V symbol was too restrictive. Accordingly the following rules are proposed to control when # may be used in the same pattern as P or V to ensure an unambiguous pattern. a) Pattern must not have # symbols to the right of the V symbol. b) If pattern has P symbols at the left end, then there must be as many 0 symbols adjacent to the rightmost P symbol as there are P symbols. c) If pattern has P symbols at the right end, there are no restrictions. If a) or b) are violated it is a schema definition error.
