Undocumented internal constants

[Hernán Giacobone]

Hello, 

I am customizing the wizard pages using the [Language] and [Messages] section, as an example:

[Languages]
Name: "spa"; MessagesFile: "compiler:Languages\Spanish.isl"
Name: "bra"; MessagesFile: "compiler:Languages\BrazilianPortuguese.isl"  

[Messages] 

spa.WelcomeLabel1=Bienvenido al asistente de actualización de [name]
bra.WelcomeLabel1=Bem-vindo ao assistente de atualização para [name/ver]

But, I need to show only the version number. 

So I replaced the above key with the following:

[ver] 

[version] 

But they don't show anything (except their literal text)

Do you know if there is something similar?

Thanks, greetings.
