Essential stylesheets load eagerly, block script > execution during parsing, etc. Not all current stylesheets are in this category by default. For example, at least in Gecko alternate stylesheets are not in this category. The behavior of Gecko for alternate stylesheets is that we do not start loading them until there are no pending non-alternate loads (though we may be changing things so that they're even lower priority) and we do not block script execution on them. As a separate issue, it's not obvious to me whether it's better to have a null OM or a CSSStyleSheet object that throws when you try to examine its rules (but not if you just want to check whether it's disabled, say). Gecko currently does the latter, I believe, but there are reasonable arguments both ways... -Boris
