I'd like to see XML Auto Completion based on the DTD
or xsd. You already know bad attributes based on this,
take a look at the Eclipse Java Editor code to see how
to activate CTRL+<space> for autocompletion. This
would help me out a lot on a daily basis as well as keep
Eclipse competitlve with IDEA.
Perhaps the same could be done for the HTML editor,
but it's not likely that everyone is going to have a <!
DOCTYPE in their page. This is especially true for
pages used for <jsp:include page=""/>
