Translate tags in Framemaker MIF file

Hi everyone,

I would like to translate 2 tags from a MIF file but I don't know how to do it, as they seem to be non-translatable. 

In the screenshot below you can find the text that I need to translate inside the tag, which is value="Navigating through menus" and also "page 17"

Does anyone have an idea of what I should do?

 

Thank you very much for your help!
