Subject: form validation parent/child tags

hey fuse-people, I just finished documenting a cool set of parent/child custom tags I co-authored for form validation. Basically they check for required fields and do datatype validation for about 10 different kinds of data.. the usual email,date,time,integer,float,ssn,credit card number,expiration date, us telephone, us zipcode and then compile all your custom error messages into one html string. Also, you can add your own custom validation and then just pass the tag a message list, which is will add to its own list of error messages.
The cool part: in the fusebox implementation, if there are any errors, the tag will cfmodule your application and send all the form variables back thru along with the error message so when the user enters invalid information, you send them back to the form and display an error message.
I've started using err_ files for calls to this custom tag. They're up on the allaire dev exchange and on www.tbcfug.org. ttyl
