Andrew Greene pointed out that the regular expression was allowing
things like 08 and 09 to appear as a field in the IP, and many (all?)
implementations treat a number beginning with "0" as an octal value.
Here's the latest solution, containing the R.E. that Andrew sent to me
which does not have this deficiency: (thanks Andrew!)
<datatype name="IP" source="string">
Datatype for representing IP addresses. Examples,
18.104.22.168, 22.214.171.124, etc.
This datatype restricts each field of the IP address
to have a value between zero and 255, i.e.,
Note: in the value attribute (above) the regular
expression has been split over two lines. This is
for readability purposes only. In practice the R.E.
would all be on one line.
