Build error App ID windows 8

[Marco_N_]

Since a few days building a HTML5-app for Windows 8 app store leads to a build error when using the correct App ID for the windows app store:

error APPX1404: File content does not conform to specified schema. The 'Id' attribute is invalid - The value '12345a.xyz.appname' is invalid according to its datatype 'http://schemas.microsoft.com/appx/2010/manifest:ST_ApplicationId' - The Pattern constraint failed.

It seems that starting with a numner is not accepted when building with XDK. The same app id worked a week ago in a XDK build.

Are there any suggestions or fixes?

It might be due to the kind of app id you are using. Windows has different rules than android and ios. May be an app id starting with number could work for ios or Android but I suspect widows doesn't allow an app id which starts with number so try changing it.
