Howto turn off error highlighting of files? Follow

Is it possible to turn of that a file in the project view is being highlighted as an error?

In IntelliJ's world, my file does have an error but not in my world :)
You see, in this specific case I have an JSP-file that other JSP's includes so it does not have a complete HTML-document in it.
There are other examples with XML-files (Maven POM's) that acts the same way.

So, it isn't so nice having a lot of red files and folders in my project view when really nothing is wrong.

Cheers
