Error when using JAXB to create JAva classes from XSD

Question

I have an XSD that describes a client's web service API. I'm using JAXB but when it parses the XSD file it throws errors. I open same XSD in Eclipse and it can't recognize those data types, so same problem in Eclipse.
Here is the XSD file:https://api-build.vitalware.com/metadata?xsd=1

xjc -d src -p file.xsd

parsing a schema...
[ERROR] src-resolve: Cannot resolve the name 'q1:DateTimeOffset' to a(n) 'type d
efinition' component.
  line 9 of file:/C:/workspace/lab/file.xsd

[ERROR] src-resolve: Cannot resolve the name 'q2:ArrayOfint' to a(n) 'type defin
ition' component.
  line 44 of file:/C:/workspace/lab/file.xsd

[ERROR] src-resolve: Cannot resolve the name 'q4:ResponseStatus' to a(n) 'type d
efinition' component.
  line 153 of file:/C:/workspace/lab/file.xsd

They seem to be Microsoft related data types which Java doesn't recognize. If this is true, is there another tool out there that knows how to link XSD's between Microsoft and Java?

Thanks in advance.
