Can anybody please share some documentation to find out the localization xml files structure for episerver cms 10 or higher. I found one article from 2013, but it seems to be out of date.
Have you looked at the Developer guide?
Yes, look at it. This does not provide all the available formats in localisation files.

Oldish post but still valid and it mentions the "Reusing localization for properties between content types", see the 'icontentdata'.
Thanks for replying Antti. That is exactly what I am looking at.
