JstlELCoreTLV

public class JstlCoreTLV
extends JstlBaseTLV

A SAX-based TagLibraryValidator for the core JSTL tag library. Currently implements the following checks:

• Expression syntax validation.
• Choose / when / otherwise constraints
• Tag bodies that must either be empty or non-empty given particular attributes. (E.g., cannot have a body when 'value' is specified; it *must* have a body otherwise.) For these purposes, "having a body" refers to non-whitespace content inside the tag.
• Other minor constraints.
