We have language specific roles, so editor of one language can not change the content in other language except the language he has access. In our scenario's, we have created 2 languages EN, SV and one user group for each language as EN editors for editing EN language specific pages and the same for SV editors too.
We noticed that SV editor can delete the page if it is translated into SV language having master language is EN but SV editor don't have chagne permission for EN langauge.
So, ideally editor is not allowed to change the content for the language he don't have access and that is working fine but still he can delete the page. Ideally he should allowed to delete their language versions but not the whole page.
I hope you getting me and if we can have this feature available in Episerver out of box, it would be good.
