Some sites have shared the desire to use some features of CSP, but not
all of them at once. For example, a site may want to utilize the
content loading features of CSP to help prevent data exfiltration, but
they may not want to be subject to the JavaScript restrictions which are
enabled by default (no inline script, no eval, etc.).
We have made two additions to the spec that we think will address these
needs:
1. Sites can opt-out of "no inline scripts" by adding the "inline"
keyword to their script-src directive.
2. Sites can opt-out of "no code from strings" by adding the "eval"
keyword to their script-src directive.
These additions may enable some sites, who would otherwise be deterred
by the JS restrictions, to adopt CSP in a limited fashion early, and
later do a full implementation as resources permit.

One thing I would find greatly beneficial is examples of how to do
things properly in a cross browser compliant way.
For example, for form validation - <form onsubmit="return checkform
()"> just works.
I've figured out (I think) how to properly attach most events
externally - like onchange, onclick, etc. - but whenever I try to
attach something to the submit event of a form, the script runs but
then the form data is posted to the action page regardless whether it
returns true or false. It just works with the inline onsubmit
attribute.
Part of the problem is IE and Firefox have different ways to attach
events, but I think there must be some concept I just don't get about
how the submit event works that isn't a problem with inline.
If you do:
myForm.onsubmit = function() {
return checkform();
}
I think it should work. Otherwise
myForm.addEventListener("submit", function(event) {
if (!checkform()) {
event.preventDefault();
}
}, false);
should work in any browser that implements DOM-Events. Unfortunately IE
does not yet.
