[Vim-latex-devel] no effect of g:Tex_SmartQuoteOpen when using \DeclareLanguageMapping in a tex-file

[<c....@po...>]

Not sure but maybe I found a exotic problem. ;)

The tex-code I attached explains itself.

I setup my vimrc like this:

   let g:Tex_SmartQuoteOpen = '„'
   let g:Tex_SmartQuoteClose = '“'

In an (nearly) empty tex-file this work fine and is correct shown in
the PDF file produced with xelatex.

But when using biblatex with apa-style and especially this line
	
   \DeclareLanguageMapping{german}{german-apa}

vim produce quotes like this, while typing

    "`test"'

This is explained in the code, too.

I am not sure from which package this \DeclareLanguageMapping comes
from. But I need it using the apa-style with German translation.

What happens there behind my vim?
