almost. Definition sent by Jason really allow empty data element, BUT it 
is slightly different to the one you can find under 
http://anonsvn.internet2.edu/svn/nmwg/trunk/nmwg/schema/rnc/XML_Schema_v03_final.rnc

Jason, could it be that we are looking in different places and speak 
about two different schemas?
