database --> xml schema generator

Does anyone know if there is a freeware/opensource application that 
generates an xml schema from a database?  (prefereably MySQL, but any is 
fine)  I haven't found anything that specifically does this.  Most 
applications I have come across advertise a database schema output, but 
not necessarily an XML Schema.

By the way, what is the status of the W3C XML Schema standards?
