My ItemDef:

Units for LBTESTCD=ALB

P21 (v.3.0.2) validation on define.xml throws an error DD0033 “Missing required ‘SASFieldName’ value for ‘ItemDef’”, this although SASFieldName is present and populated.  
The error message should probably be that the value for SASFieldName is too long (looks as it is restricted to 8 characters).  
I presume the reason is that XML-Schema error "_cvc-attribute.3_ - … _is not valid with respect to its type …"_ is not correctly interpreted by the software.
