[PATCH] jakarta-servletapi-5: JSP 2.0 API updates

[Mark Roth <ma...@sun.com>]

Here are the latest round of JSP 2.0 API updates.  Some changes will 
need to be made to jakarta-commons-sandbox/el before applying this patch.

I also made a couple of changes to the JSP 2.0 examples in accordance 
with these changes.


jsr152/src/share/dtd/jsp_2_0.xsd:
jsr154/src/share/dtd/jsp_2_0.xsd:
     - Expanded on description for taglibType complex type.

jsr152/src/share/javax/servlet/jsp/tagext/SimpleTagSupport.java:
     - Change getJspBody() to be protected
     - Change getJspContext() to be protected
     - Change the jspBody field to be private
     - Change the jspContext field to be private.

jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java:
     - Changed so that Strings of the form "abc${1+1}def${1+1}ghi" cannot
       be parsed or evaluated.  Only one expression can be parsed
       evaluated at a time, and no static text can appear.

jsr152/src/share/javax/servlet/jsp/JspWriter.java:
     - Changed javadocs for print() methods to indicate that the
       resulting text is written to the writer, and not converted to
       the platform's default character encoding first, which would
       make no sense.

jsr152/src/share/javax/servlet/jsp/tagext/TagInfo.java
     - getTagName() - Clarified that name is always returned (cannot
       be null)

jsr152/src/share/javax/servlet/jsp/tagext/Tag.java
     - Accessibility fix.  Added img alt tag.

jsr152/src/share/javax/servlet/jsp/tagext/BodyTag.java
     - Accessibility fix.  Added img alt tag.

jsr152/src/share/javax/servlet/jsp/tagext/IterationTag.java
     - Accessibility fix.  Added img alt tag.

jsr152/src/share/javax/servlet/jsp/tagext/VariableInfo.java
     - Accessibility fix.  Added img alt tag and table summary tag.

jsr152/src/share/javax/servlet/jsp/el/ExpressionEvaluator.java
     - evaluate() - Removed defaultPrefix param and allow FunctionMapper
       to mutate after call.
     - parseExpression() - Removed defaultPrefix param and allow
       FunctionMapper to mutate after call.
