As always, please let me know if there are any questions or concerns.
Change summary:
---------------
jsr152/src/share/javax/servlet/jsp/tagext/VariableInfo.java
- Fixed incorrect wording from last patch, for variable
synchronization.
jsr152/src/share/javax/servlet/jsp/tagext/TagExtraInfo.java
- Fixed wording to preserve forwards compatibility for existing TEI
implementations.
jsr152/src/share/javax/servlet/jsp/tagext/TagInfo.java
- Fixed default implementation of getVariableInfo() to return a
variable for the id attribute, if specified.
Clarified intent in javadocs.
jsr152/src/share/javax/servlet/jsp/tagext/TagData.java
- Fixed getId() description, as we're not returning the jsp:id in this
case.
jsr152/src/share/javax/servlet/jsp/tagext/BodyTag.java
jsr152/src/share/javax/servlet/jsp/tagext/IterationTag.java
jsr152/src/share/javax/servlet/jsp/tagext/SimpleTag.java
jsr152/src/share/javax/servlet/jsp/tagext/Tag.java
- Clarified javadocs w.r.t. variable synchronization
jsr152/src/share/dtd/web-jsptaglibrary_2_0.xsd
jsr154/src/share/dtd/web-jsptaglibrary_2_0.xsd
- Removed fragment element under variable element, as fragment-scoped
variables are no longer supported.
