A JSP container may (optionally) support a jsp:id attribute
to provide higher quality validation errors.
When supported, the container will track the JSP pages
as passed to the container, and will assign to each element
a unique "id", which is passed as the value of the jsp:id
attribute. Each XML element in the XML view available will
be extended with this attribute. The TagLibraryValidator
can then use the attribute in one or more ValidationMessage
objects. The container then, in turn, can use these
values to provide more precise information on the location
of an error.

public ValidationMessage(java.lang.String id,
java.lang.String message)

non-null. The value of id may be null, if the message

attributes were passed on. If non-null, the value of

passed into the validate() method.
Parameters:
