Description Ryan Lubke 2002-03-18 21:42:56 UTC 
Given:
  <c:out value="< > , ' \" &" escapeXml="falbse"/>

No exception is thrown, but according to section 2.7 of the Public Draft spec,
if a dynamic attribute with with a fixed set of values is provided an invalid
value, an exception must be thrown.

I believe section A.7.4 applies here too; let's revisit only if it's still an 
issue in PFD.
Comment 2 Ryan Lubke 2002-04-11 15:15:17 UTC 
If section A.7.4 is applied, then an Exception should still occur.

  3rd bullet item:  Otherwise, if A is a String, and Boolean.valueOf(A) throws
                    Exception, error.


I'm now expanding this issue to include <x:out> as well.
Comment 3 Shawn Bayern 2002-04-17 21:25:33 UTC 
I believe this is no longer an issue now.  Do you agree, Ryan?

Reasons:

- In PFD, we changed the wording to "valid string values". 
  (I joked that not just booleans, but numbers too, have a "fixed set of
  valid values.")   :-)

- Boolean.valueOf() doesn't throw parse errors; it collapses unrecognized
values   to false.
