WIX0070 (A reference to the TARGETDIR Directory was removed) points at nonexisting FAQ information

[PerMildner]

Using wix --convert, I get the following error:

error WIX0070: A reference to the TARGETDIR Directory was removed. This can cause unintended side effects. See the conversion FAQ for more information: https://wixtoolset.org/docs/fourthree/faqs/#converting-packages (TargetDirRefRemoved)

However, the page at the suggested URL does not contain any mention of WIX0070 or TARGETDIR.

wix --version
