I’m using the Microsoft Visual Studio 2008 xsd.exe tool to generate .NET source code from the FIXML XSD schema.

Most of the files generate fine, but I’ve come across these errors:

fixml-ordermasshandling-base-5-0-SP1.xsd and  
fixml-ordermasshandling-impl-5-0-SP1.xsd:

“The datatype ‘[http://www.fixprotocol.org/FIXML-5-0-SP1:AffectedOrdGrp\_Block\_t](http://www.fixprotocol.org/FIXML-5-0-SP1:AffectedOrdGrp_Block_t)’ is missing.”

And for fixml-datatypes-5-0-SP1.xsd:

Warning: cannot generate classes because no top-level elements with complex type were found.

Hopefully there’s an easy fix.
