[wix-users] Empty WixVariable

I do not think WiX variables have anything to do with MSI. It is compile-time only thing.

I believe empty Wix Variables get deleted when the execution of MSI begins

According to documentation (http://wixtoolset.org/documentation/manual/v3/xsd/wix/wixvariable.html<https://urldefense.proofpoint.com/v2/url?u=http-3A__wixtoolset.org_documentation_manual_v3_xsd_wix_wixvariable.html&d=DwMFaQ&c=nFCqHnrrxvlLMYTrG_iNtg&r=ehn4KDOoNQKU8FFhhOOToxxpuqGQWkAWqOXxDtLAcj8&m=mKcFCg1DNrs5A2BhArwlNgnGrFcXjx0sPY81jYPSAuc&s=cGrQEAMct0GhIxxveQ5HxHkklusVX5C7Zvwk3zsJ_6M&e=>) WixVariable Value cannot be an empty string.

1. What if I need it to be entry string/null?

2. Settings WixVariable to empty string does not result in error (WiX Toolset v3.11.0.1701). Does it mean the documentation is incorrect and I can rely on this behavior? Or is it a bug that will be fixed in the future versions?
