Re: No validation performed with recurringDuration and its derived types

[Jeffrey Rodriguez <je...@hotmail.com>]

Mr. Fernandez,

I am currently working on getting the implementation of the date/time
validators.

Regular expression are only being used on the Pattern facet.

So if you have a Pattern facet it will use the regular expression
parser.

The implementation that I am working uses SimpleDateFormat.


I will post them within the next couple of days.

Thanks,
              Jeffrey Rodriguez
