According to the documentation for the Requires elements (http://wixtoolset.org/documentation/manual/v3/xsd/dependency/requires.html), it can be put inside of a Product element.
I am wondering if that's a feature that hasn't been implemented yet. What I'm saying is, it sounds like the WiX team would like to have MSI packages themselves register as providers and requires packages. But currently, perhaps it's only something that works with Burn bootstrappers. Also, the MSI in question would have to be authored with WiX and use the DependencyExtension.
