S2S schemas rely on the so-called multi-import technique where the same 
namespace is imported via different schema files. The XML Schema spec 
says that conforming processors are free to ignore any subsequent imports 
or they can try to process subsequent imports and accumulate the grammar. 
For more background on this issue see this blog post:

XSD 3.2.0 uses the "ignore" approach. For the upcoming XSD 3.3.0 we have 
implemented the "accumulate" approach. The first beta for XSD 3.3.0 will
be released tomorrow. I have tried it on the S2S schemas (v1.3.1) and
was able to get past these errors (with 3.2.0 I got errors similar to
yours) but there are still a few issues that need to be worked out
(automatic anonymous type naming leads to unstable conflicts). I will 
work some more on this schema tomorrow after the beta is released and 
will send more information then.
