Image a capture of my project

Netbeans is a great IDE, I really enjoy creating new apps on it, but now when I installed Netbeans 7.4 I have my web project full of red lights marking the jQuery plugins that worked really fine: In Javascript file marking the Javascript regular expressions, In CSS marking CSS expressions, in HTML marking 'incorrect' HTML (Are you serious?), 

This didn't happened to me in versions of Netbeans <= 7.2 so it seems like you have been more 'strict' in error checking of that type of files, and please understand that maybe there's and error in that files: but I have no control over that, these are jQuery plugins that I download for third party developers, so what I do? Go and download new versions of the plugins that probably are incompatible with versions of other plugins that I'm currently using (You know, jQuery and jQuery have suffered breaking changes in the versions) No way!, So as a workaround I renamed the file extensions so that files ared not recognized anymore as CSS, Javascript files and I don't get any 'errors' for that files, but it is not the real solution, the solution here is that if you want to be more strict validating static files you should give the user an option to disable that behaviour and that option should be in the Configuration something like 'Enforce strict validation of static files', That will be really a good solution, welcomed to every HTML5 developer,

Thank you so much for the great work.
