Open XML Schema Imports Question

I am trying to compile (bind) the ms-xlsx schema's defined on MSDN's developer MS-XLSX Appendix A: Full XML Schema (This message board would not allow me to post links)

However, the compile fails because I do not have access to any of the imports (e.g. orel.xsd). It's great MS provides thes MS-XLSX schema's however they are useless to me without their imports also being available. Can someone please provide me these additional schema imports?

Thanks in advance,

Noah
