Information defined in info section are not available as build-in variable during compile time

I tried to use build-in variables like $APP_NAME $APP_VER in a html file used as resource for the HTMLInfoPanel. But it looks like build-in variables filled with values from the info section are not available during compile time. I currently could workaround the problem by defining separate variables containing application name and version in the variables section. Unfortunatelly this leads to duplicate entries in my installer configuration file for application name and version.
