Paul Benedict resolved STR-3055.
--------------------------------

    Resolution: Not A Problem

After playing around with the app, it became obvious that the cryptic "!empty pageScope" is a way of demonstrating EL. Yes, a verbose way of getting true or false, but a sure way of generating those values through an example.

> The EL-Example has lots of 'disabled="${!empty pageScope}". This seems hugely confusing - why say that and not just 'true' or 'false'.
> At the minimum, need to explain when it's happening so people know a field is meant to be disabled.
