How can I avoid a warning about a child document of a different class?

[Christian Ridderström]

Hi,

I have a child document containing acronyms and abbreviations. My idea was 
to include this child document in several different documents and to use 
branches to select the list of abbreviates I actually want.

However, with the master document being of a different class, I get a 
warning about this differnce each time I compile the document...

Is there a way I can disable this warning?

Or alternatively, some other way to maintain a rather lengthy list of 
abbreviations that I'm likely to include in other documents?

Best regards
Christian
