This set of warnings tells you that a bunch of elements in your schema
don't have the 'type' attribute and default to being of the xsd:anyType 
built-in XML Schema type. If this is intentional then you can disable
these warnings by adding 

--disable-warning F001

to the XSD command line.

This warning tells you that your schema uses polymorphism but the
generated code will be polymorphism-unaware unless you specify the
--generate-polymorphic option. For more information on support for
XML Schema polymorphism, see Section 2.11, "Mapping for xsi:type
and Substitution Groups" in the C++/Tree Mapping User Manual:

This error tells you that the XSD compiler does not know how to map
the urn:ietf:params:xml:ns:forces:lfbmodel:1.0 XML namespace to C++
namespace. You can use the --namespace-map option to provide a mapping,
for example:

--namespace-map urn:ietf:params:xml:ns:forces:lfbmodel:1.0=lfb1_0

See Section 3.3, "Namespace Mapping" in the C++/Tree Mapping Getting
Started Guide for details:
