Date in xml schema

Hi,
the date datatype (type="xs:date") in schema definition supports only 
"YYYY-MM-DD" format but I need to have my date in "DD/MM/YYYY"(Brazil 
format) format. Is this possible in schema 1.0? If no, i think that is 
must be part of requirements of new version(1.1). Please, i'm waiting a 
reply...
