Since you haven't provided any concrete information on what you
have tried and what exactly doesn't work, I can only say that
the --namespace-map option has the following general usage:

--namespace-map http://some-oms-website.mil/=SomeCppNamespace

It is indeed very hard to misuse.

This is not an error. It is a warning.

In XML Schema every global element is a valid document root element.
But global elements are also often used for other things (e.g., to
'ref' in multiple places or for substitution groups). At the same
time there is normally (but not always) only one actual document
root. As a result, when your schema has multiple global elements,
XSD will assume that all of them are valid root elements and
generate a set of parsing/serialization functions for each of
them. Since this is normally wasteful (code bloat), XSD issues
this warning.
