well, with 3396 we almost have what we need:
1. jsp code exceptions are no longer marked as errors, but they are now marked as needing some treatment, which is false. moreover the ide suggests to insert a static import, which has no relation with the issue at hand
2. now we can turn off html "validation" on a single file (on my xp changing this setting makes the fatal errors regularly fill with menacing messages), but how to globally turn it off, and eventually turn it on on a single, peculiar file (making the dearing assumption that there ever will be a need for html validation :) ) ?
p.s. practically any kind of html is marked as invalid :-D, but this is quite secondary
