[MOBY-dev] JAX-WS BioMoby API (2nd round).

[Mark Wilkinson]

...unless there has been some new changes in XML Schema that I missed!  I  
admit I haven't looked at it since my conversation with a guy from the W3C  
XML Schema working group, who confirmed to me that, in his opinion, it  
couldn't be done... I took that as "the word of God" at the time, but that  
was probably two years ago, maybe longer...
