[support] edit taxonomy term by role or uid

[Alison]

Is there any way to limit who can edit or use in any way a specific 
taxonomy term by role or userid?

I am going to be using a flexinode for content and want any 
authenticated user to be able to create content in it. I have multiple 
taxonomy terms attributed to it but there are some that I only want 
specific people to be able to edit or attribute to the node since it 
will be sensitive/controversial material.
