[wix-users] Empty WixVariable

[Alex Ivanoff]

Sorry for duplicate question, I really need an answer.

According to documentation (http://wixtoolset.org/documentation/manual/v3/xsd/wix/wixvariable.html) 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?
