Looks like my XSD4MXML tutorial post was like so 1999 'cause the boys over at FDT delivered the beta release 3.2 with MXML support the 13th of March already. I can't keep up these days. What are you waiting for? Get it now! 

For those of you who want to get some MXML support in FDT I thought I'd share this little tutorial. I can't take credit for this as it was the guys from FDT who pointed this out at recent visit to LFPUG and Adobe MAX Milano way back in 2008. Lets hope we get FDT to support MXML natively so this isn't required but until then here goes. A small caveat, this will probably not work in Flex 4 as I remember them removing the mx namespace for the framework.
