Follow-up date formatting question

I need some help formatting the output of dates using v1.0.3.

In searching the archive ... on May 12, 2004 Eric Vasilik wrote:

Was such an "option" added to globally format dates?

If not, what I need to do is have the output of dates be of the format: 
yyyy-MM-dd'T'HH:mm:ss.SSS-zz:zz .  What xmlbeans creates with toString() 
or xmlText() is: yyyy-MM-dd'T'HH:mm:ss.SSS'Z'.  I have a routine that 
uses SimpleDateFormat to convert a Calendar into a String of that format 
... if that is of any use.

One way to solve the problem is to parse through all of the xml and 
reset the Date/Calendar with a XmlCursor, but that is both time 
consuming, and requires modules that don't manipulate the xml in any way 
to have knowledge of where each date is located in the schema ... which 
throws a lot of re-use out the window.

Any help would be appreciated.

Thanks,
