[wix-users] Wix 4 localization not working as expected

[Alan Sinclair]

Is localization defined differently in WiX 4 than in WiX 3? Or perhaps
included differently than -loc xxx.wxl ?

Light.exe 4.0.0 is giving
    error LGHT0102 : The localization variable !(loc.PackageDescription) is
unknown.

PackageDescription IS defined, in a .wxl which is referenced on light's
command line:
(This same command line works fine with WiX 3.11):

    light -spdb -sw1076 -ext WixUtilExtension  -ext WixUIExtension  -o
works-en-us.msi   -dWixUILicenseRtf=EndUserLicense.rtf  *-cultures:en-us
-loc wsstrings-en-US.wxl*  wsbase.wixobj  wscore.wixobj  wscustom.wixobj
 wslocals.wixobj  wsoptions.wixobj  wsqtquick.wixobj  wsswiftshader.wixobj
 wswixui.wixobj  wsWelcomeDlg.wixobj  wsWelcomeEulaDlg.wixobj
 wsInstallScopeDlg.wixobj  wsProductModeDlg.wixobj

defined.
