Subject: Re: To get things started.... Data formats




David and Todd:

The @ and the $ are not valid name characters in XML so they cannot
be used in either element or attribute names.  

Why not use the ISO 8601 and W3C Date format of CCYY-MM-DD or 2000-08-18.  
Parsers will eventually recognize this format and date datatype for free.
