error-list-name	optional	The name of the error list	Defaults to "error_list"

Child Elements

Any <condition> child element

optional

A condition to test

Info

title	Proposed Changes

Currently, the title attribute is optional. Keep the title attribute optional but have it default to the file location and line number.
Eliminate the error-list-name attribute.
Currently, the child element is optional. Require at least one child element.
