xml:lang

Hello, I am converting an EPUB-file to docx using calibre. In the text there are several description lists, i.e. glossaries, With the English and the translated Norwegian text:

<dl><dt>mind: </dt><dd lang="no" xml:lang="no">sinn</dd>

My question is: Will this information (xml:lang) be transferred to the docx-file, so that the synthetic Speech will change accordingly?
